Thanks Eric. Awesome video for anyone thinking of getting into porting heads. It is an art that is worth preserving. Back in the old speed shop days, We had a "head guy" He was really good and very expensive. He would never give any details about how or what he did. You pay and you make power. All the top builders in the area used the same guy. David Visard recently referenced you and was pleased with your work. Good endorsement. Keep up the good work Eric.
Hello friend, I have a small compressor and I can't buy an air die grinder because it would be charging air all the time, im looking for an electric die grinder, would you recommend the Makita G0603, can sand cartridge rolls be used in it? A friend told me that The electric grinder sucks to sand with ,easy way to bend the mandrel. I need to do some light porting with power tools at home.im thinking on makita gd603 or a Foredom SR, could u help me ? greetings and excellent channel my congratulations❤😊 regards from Spain.
Good stuff Eric. Just a hint for anyone who reads this, I do a lot of aluminium work. If you are having trouble with cutting tools biting in, just dull the cutting edge a fraction. Often on new drill bits I will run a diamond lap, or a small stone, lightly over the cutting edge to take the very sharp edge off. If you do this, you will find that it still cuts we, but doesn't dig in aggressively. Regards Greg
Oddly I found once when I needed to remove bulk of material with burr that weld spray, that anti stick spatter spray works like magic to stop burrs clogging. I recommend to test that.
If I didn't live in Northwest Ohio I would come and take a class from you. I am a retired truck mechanic of 50 years have been working on asphalt circle track engines for many years. I have plenty of time on my hand. Thank you for the video!!
I recently bought a cheap kit of burrs for aluminum on amazon. They fit in a Dremel. I used them to port an LT1 intake from a Gen2 LT1. Much to my surprise, the $15 burr kit did a great job! I did break one burr, but I got by with another one from the same kit (different shape). Originally, I bought them for a different purpose, but they worked great on the short-runner intake.
Eric, Your video is really helpful, but, as you said, for us DIY individuals, Just wondered if you could list the part numbers with the items, a lot of the cases and packages that held the items were flipped over in this video, this would be a great help for ordering the right items that you use.
@@WeingartnerRacing def down with a class/school. i get asked to do dirt track stuff all the time. esp cast iron stuff. retired and lookn for something diff and thats right up my alley. even if its jus me in there
CHA website isn’t taking orders The SE6 which is 6” shank 1/4” stem 1/2” egg shape is my most used cutter I use a Dotco extended grinder that is extremely light and quiet, but is s 600$ grinder
I know this is a little late and you might not look at comments from older videos. But was watching another video a inside look of an n/a 900hp sbf and he was going in depth on how they ported blue thunder heads and raised the intake runners and how they put a W shape in the floor made me think about some of your work and how you like to test new things. Thought you might like it
Thanks Eric. Another great video. I have the Fordom electric as well, but I only use it for fine detail chamber work. It's 1/8 inch and I also have a very small 90° head for it because I used to do two stroke transfer ports. It's great because it has a foot pedal. I use air for every thing else, because...well, I just have it and have for many years. BTW, I love your videos and am learning still, even though I have been grinding on heads for almost 40 years. I hate to think of some of what I destroyed many years ago.......
You give away your information for free and people complain when you want sit all day to tell them how to do you out of work, excellent show, all the best to you and your loved ones
Hey Eric, do you use a vacuum system while you're porting? I have OCD, so I have to keep one running even while porting. I can't stand the filings going everywhere!
Thanks for another great video Eric! Did I hear you right? You port your throats by hand instead of using a cutter? I am curious because I have not been able to find any information on cutting or grinding valve throats. I would think you would be more consistent using a cutter and a machine vs doing it by hand. Still learning!
Gday mate from Australia. I really appreciate the time and effort you put into these videos to try and give the first time head porters some good tips and advice on getting the best possible performance out of various head types. Along with Dave Vizard, Headflowinc, and other reputable engine builders videos, I have gained a great insight into the importance of correct head porting techniques, what to do and NOT to do. This video provides great guidance on what BITS I need to purchase for my own head porting project. Many thanks. Just on that Eric, I just wanted to confirm setting the throat diameter is between 88-90% of the valve diameter which in my case is a Holden V8 308 intake of 1.94 inch and the same for a 1.49 Exhaust valve. With the bowl area size, is there a % size this needs to be related to the valve size or runner size/area????Any rule of Thumb?? I understand you use porting in the bowl area to help slow and turn the flow into the seat/Throat. And you can use port bias to help slow plus direct the flow into the chamber which creates a venturi effect. With my Holden heads, the intake runners arrive at the combustion chamber at different angles EG one has a longer runner side aimed at the Cylinder side while the next runner aims at an opposite angle, the longer runner side goes to the NON-Cylinder side, which I see might cause some problems when using Port Bias while trying to keep the runners uniform. Holden V8s use an SBC intake profile unlike the SBF layout. Anyway again I really enjoy all the videos you make, your obvious experience, knowledge, skills and they way you explain things that one can understand. Thanks Eric.
@@WeingartnerRacing Not sure if I could send through to you a picture or diagram, just I appreciate your knowledge. If I could that I would be so grateful given how much you know about porting heads.
I wish you did cast iron (street stock rules). Having done lots of them myself, I know why you don't 😁. Thanks for sharing your knowledge and tools. I really enjoy the content. #motorhead

Is the Foredom SR enough for a beginner? Or do I need the TX? 😀
After you buy all the tools. where do you purchase some courage to cut your new truck flow heads? Asking for my neighbor.
If I was close to your shop I would absolutely be at a class with you sharing your knowledge. Thanks as always
If you spray the burr with wd40 or pb blaster they wont clog up. Same goes for sand paper rolls and cut off wheels. The aluminum cant stick.
I cut them all down to about 4 in anything longer than that and if you accidentally go to high speed they'll bend and scare the living s*** out of you

Would you ever do a porting class like joe móndelo used to do?
I saw a tool on your bench that’s an honorable mention, a set of snap gauges, they’re cheap from hobo freight.
All the stars align. I was looking at your videos last night to see what tools to get to port my intake manifold

Working on aluminum with readily available stuff, WOW, we got it so easy compared to 50 years ago.
I would show up!
Thank you for your knowledge.. USA 🇺🇸
Check out McMaster-Carr for you bits... mine were cheap for cast iron, double cut. Great videos!!!
I'd show up

Several are available on my online store.

Where did you get that inverted taper radius carbide for the short side radius
I put a dimmer switch, inline, with my electric grinder.
What happens when the port has mirror finish?
👍👍👍
Hey Eric, do you use a vacuum system while you're porting? I have OCD, so I have to keep one running even while porting. I can't stand the filings going everywhere!
I don't use a vacuum system. I don't want more sound.

My throats are offset which is impossible with a seat and guide machine.
Eric, what company did you say you got the rounded reverse cone burrs from? I’ve been looking for those forever!
buckeye carbide.
Very informative video. Thank you for sharing your knowledge.
Thanks for watching.
Looks like some strange lollypops

Without seeing a Holden head I don’t think I can give proper advice on it.

Thanks Eric. What is used for a Burr finish?
Its where you use the burrs for the finish.
@@WeingartnerRacing sorry I'm talking about the rough finish on let's say on intakes.
In Australia, the 3 burrs you use are $135 dollars each . Yours are cheap
Wow
Yep.
In Australia they are expensive af. 😳
