    They should have flow tested that dirty old head, then hot tanked them and flow tested them again and then flow test them after all the port and polish work. I thinking it would have added a great deal of information as to what to expect between "as cast and dirty", "as cast and cleaned", and then ported and polished flow numbers. Seeing the difference in the cfm flow would have been a great way to show (prove) the benefits of the work.

      It would also be good to see what effect port matching the intake had on flow. Results are inconsistent from what I've seen and read. Some say it makes no difference. Some say they've seen losses after port matching.

    50 years ago I put 5 hp Briggs and Stratton valves in a 3 hp Briggs and Stratton engine and milled the head on my dads sander in his woodshop, to hop up my mini bike, ended up kicking but on those Honda mini trails, years later I put Chevy Corvette valves in my ford 289 heads and ported it like this video, it turned my Mustang on big time.

    I used to build racing 2 stroke engines and got to know porting very well. Never did a car engine but by looking at the set of heads on my dads 289 Ford sitting on the bench there’s some pretty rough casting on those things. He’s gonna have me smooth them up. I got all the tools, looks like I can get most or all of it with just a straight pencil grinder. Doing transfers on 2 stroke jugs you need 90 degree or at least 45 degree pencil grinders. I even have a smaller one you would typically see used at the dentist for chamfering edges and tight corners. Looks like fun, we have a flow bench at work in the engineering lab and I might see if I can slip the manager a $50 and bring the heads in on a Saturday for shits and giggles.

    Great tips for a beginner and fun to watch. I thought the porting advice was good, but I would have mentioned that more runner volume might give you more flow, but less power, depending on the head, so don't go nuts hogging it out. Velocity matters. I also protect the seats with duct tape. Enjoyed the video!

      Whatever you do just remember marine engines have different specifications than automotive engines! Also most of the components on the engine are regulated by the USCG, Not to mention that using automotive grade parts is extremely dangerous, foolish and can cause some serious issues! When I rebuilt my marine engine I just did a little cleaning and port matching to my cylinder heads! I rebuilt my engine when I purchased my boat in 1995, It is a 1987 GM 4.3L with a two barrel carburetor! Now it is a 4.3L with a little head work, upgraded valve train,small cam, Rochester Quadra jet and headers! And now because of the increase in horsepower and torque I was able to change from a aluminum prop to a bigger stainless steel! If you can do the work yourself it is most definitely worth it! You may ask why install headers on a V6, Because about 21 years ago OMC stopped producing the 4.3L one piece manifolds and no one was producing 4.3L OMC 1 piece aftermarket manifolds yet! My boat was high and dry on the trailer for two years while OMC was giving me the runaround, Then someone told me about a company in Australia that makes direct replacement stainless steel headers for almost all of your marine engines! Those headers we’re worth every penny, They have been on my boat for about 15 years and still look like they were just installed! I live in New Jersey and my boat is docked in salt water all summer every summer and I use the boat every weekend! If you ever have to replace manifolds I suggest you check out this company, Hi-Tek Marine! They are much lighter, take up less room, lower engine compartment temperatures and you will notice horsepower gains and a decrease in fuel consumption! Not to mention you will never have to replace your risers or manifolds again! I have no affiliation with the company I am just a mechanic who was lucky enough to be raised by my grandparents who has a beach house with a boat, And when I come across a product that performs above and beyond expectations I like to pass on the information! Good luck

    I worked in a foundry as a young man as a casting finisher. On our lunch hours we worked on a guys engine to port and polish it. We took it to the limits by polishing the rocker valley for oil return. We polished the entire block inside and out as well! Did the same for the intake manifold but it was aluminum. The best lubrication for working aluminum is beeswax. 1966

    Before you port your heads, you should go to a junkyard and buy some non rebuildable cores. That way you can make every mistake possible before you even attempt to work on your own car.
    Years ago, I wondered why I don't see aluminum 4V cylinder heads don't get ported often. I went to a junkyard, and bought a 4G63 head that had a timing belt snap. The core was junk, so I was free to screw up if I wanted to. I found that there really wasn't that much to reshape. Often the most an amateur can do is sharpen up the area where the individual port splits into 2 valves.
    The other advantage of doing a P&P to stock heads is that you can have a numbers matching car, but have more horsepower anyway. In addition, there are many engines that do not have new castings.
    That burette is also great because you can see how consistent your porting is. Your porting will vary, plus some heads had less than great casting consistency to begin with. Next, use it on the combustion chambers to make sure they all match. It ensures the compression ratio is the same on all cylinders. Besides, those numbers could vary based on casting flaws as well.
    Early cylinder heads should have hard valve seats pressed in when rebuilding. Those heads were built with the assumption that leaded gasoline would protect valve seats.
    When you have turbos, crankcase ventilation becomes even more important.
    17:11 Aren't those check valves the kind of thing you would find early old AIR pump smog engines?

    This guy isn't going to give you good advise. Been watching him for years. This video talks about gasket matching. What about the intake or exhaust manifolds? The gasket doesn't determine porting, the manifold does. Good baseline though. And you want your exhaust ports smaller than the primary tubes. Don't fuck your heads up. just saying, This shit takes hundreds of hours to master. Notice that there aren't any before or after flow bench tests. Even though he has the resources.

      I mean we are talking about dudes using scotchbrite pads on a grinder risking chewing up the surface. If you look when he is polishing the combustion chamber he does hit the head gasket mating surface. Not that it is that big of a deal but the little stuff goes a long way.

    • @ahoneyman

      It's a half hour show. He smoothed the exhaust port, cleaned up any obvious casting flaws, and basically indexed the ports to the gasket. This will help most engines in most street applications. More than that requires a lot more engine info and some interesting physics.

    • @mickpatterson6402
      @mickpatterson6402 3 роки тому +2

      Sure it was a half hour show. I don't know what that has to do with anything. It probably took them 10 hours to shoot it. Have you ever ported anything? I have. My point is that, this guy attracts an audience of wannabes by making shit look way more simple than it is. Making people confident that a half hour video is all you need to understand what you're doing and that it's just that easy. They are selling a show. not viable training by any means. I'd bet he trashed those heads in the process while acting like it's a leisurely afternoon activity.

      It depends on your attention to detail and if you have some support by people who know more than you. I have a friend who is from a construction background decide in his 50's he wanted o build a GTO drag car and race it. Think he knew what he has doing? Hell no but he asked me to help him and advise him. Car is running quite nicely and he is having a blast. You know all those warnings that were even in this video about "don't do this or else bad shit happens"? Well any seasoned mechanic has a lot of them and thats because either we royally fucked up or witnessed someone else do so and never forget it. Benefit from that body of knowledge and thanks to the internet there are a lot of people out there in forums and such who are giving this knowledge away for nothing. Take advantage of it, and do your homework first but don't be afraid to try something new.

    • @charlesfields7908
      @charlesfields7908 3 роки тому +3

      From factory there is already a pressure release system installed. Hince smog pump, e.g.r, pcv valve. Alot of times there is the vent cap on top of the valve cover that runs back into the intake or there is just a hose running from the valve cover with a pcv on the opposite side of the motor or both a vent cap and a pcv. Sbm has the cap with pcv. Unless your running high compression or forced induction the basic factory set up does just fine. Hope this helps 👍

      @agcacustoms2852 3 роки тому +2

      From what I’ve seen before is that if the gasket opening is bigger than the port then you port it to match the larger size of the opening on the gasket. You could always make your own gasket if it’s too much trouble or try and buy a gasket kit with a variety to see what fits your application.

    • @craighansen7594

      I do match the header port area to the cylinder port. You might need to add a little metal to the headers, mig welder works for this. If you don't have use of a welder just don't grind it thin. You could have to improvise on the bolts and get some with smaller heads.

    Don't valve cover breathers do the same thing as the $40 kit for evacuating crankcase pressure? I would think so, and I also believe it would be cheaper and easier for a backyard mechanic to do.

    • @nashvilleoutlaw
      @nashvilleoutlaw Рік тому

      Technically the factory breathers releave the crankcase pressure from the crank spinning. Pre 67? I believe didn't have breathers and would build excessive pressure on the passenger valve cover or excessive vacuum under the drivers side valve cover. One side would get sucked in or the other would get blown out. A friend of mine had a 64 El camino 327 and blew one about every trip from TN to Chicago and always kept an extra set in the car. Of course he kept it over 100 most of the way and no overdrive so no telling what rpms he was running😂😂
