All those of you listed below ----- Thanks guys.
Your welcome Dv. I suggested that you raffle off a free port job on a set of their heads
Thank You so much for the information Mr Vizard. I'm a turbo 2.2/2.5 enthusiast myself.
Hello sir. I am an engine tuner, on Austin Mini and other English cars, my workshop is in the south of France. it is thanks to you and your book that I was able to learn my trade. thank you sir.
Looking forward to learning more about valve seat angles.
Thank You Mr Vizard. I've been a turbo dodge enthusiast since the GLHS vs GT350 Hot-Rod magazine article in 86
This knowledge is the best horsepower for those who want more than that
Great information!! Thank you! Please try a Superbike head, would be great to hear your thoughts about them.
Not to sound ungrateful but i cant get enough. Thanks DV
I'm listening buddy 👍 can't wait for the next one
This is awesome I love Richards channel. Every video on David’s channel is gold. So many years of experience to educate the rest of us.
Thanks for your efforts to explain these nebulous concepts of dynamic flow. I don't pretend I have any solid grasp but am gaining some insights into what happens in the process. I have a gut feeling that this process with all its inherent variable changes as ice engine rpms increase through the operating parameters is what can give an engine its feeling of "life" versus the seeming digital "deadness" of an electric motor driven vehicle.
I can't thank you enough DV for all the investment that you made and to sharing your wealth of knowledge with others. I know I have learned so much from you… and have so much more I can learn. Thank you for all you do
Mr.Vizard thank you for the video channel and all of your videos. I wish you all the best to continue a healthy recovery for your health. I have been glued to your articles every since the very late 1970's early 80's. I am planning a project turbocharging a chevy i6 for a streetrod and would enjoy a video on the Siamese intake port and valve angle mods for this style head. Thank you ever so much for sharing your knowledge and hard work, so that the layman May gain this knowledge.
Thank u David. On these 2.2l videos
My interest is 4 valve per cylinder Japanese engines. I still find these videos helpful. I would like to see more from the Golden rules.
Yes sir - coming up soon.
@@DavidVizard thanks. I really appreciate it
@@DavidVizard I think your videos are very educational for us learners. Do you have any videos on your Minni head porting. I am wanting to port a 1956 holden grey motor 6 cylinder head that gas Siamese intake ports and bath tub chamber. Just like the Minni head
Thanks Darren Thomas. From Australia
Thank you for all the hard work you put into these videos!
Two great gentlemen doing work with each other, I love it
Thank you for putting the episode number in the description, but you can also put it in the title and it makes it easier to find them when you have references to them on other videos. :-)
I can't wait to se this finished, love the oddball stuff!
And, thank you for your time! 🙌
Thanks!
Awesome
Great vidja 🤙🏼
Looks like Richard is leaving a good bit of power on the table if he doesn’t really lift those valves!
Hello David. I really think your your videos are very educational for us learners. I am wanting to port a 1956 holden grey motor 6 cylinder head. It has Siamese intake ports like you Minni head and also a bath tub chamber I am in Australia and was wanting to know do you have any of your mini head porting videos I can watch. I have tried to find some with no success. Thanks for your help
interesting vid.
Great improvement on limited
Head a while back you said
That you would tackle Jaguar
V12 head will that still
Happen and would that
Valve seat angle be improved
Also like this one great
Information as always Professor.
Cant wait til the next vid comes out. You should raffle off your porting skills on someones self furnished heads if they win the raffle. I would most defintly buy my share of tickets
Any idea when this project is going to be finished so we could see Richard Dyno the results?
How steep / shallow can you go with valve seat angles, before you start running into reliability / sealing issues?
Seat video coming up.
@@DavidVizard
Looking forward to it. Thanks!
Is there any rule of thumb for desirable swirl RPM vs flow or is more swirl always better?
are sodium filled valves an advantage in this application ?
Sodium filled valves I would say are beneficial if you’re going to making extreme heat on the hot side of the turbo. Outside race and specialty applications I’d say it is a wash.
Time is money....
Hi David, I am in the process of rebuilding my Subaru EJ257. The lical speed shop I am using is shooting down any mods to the heads. They claim the stock heads flow poorly. They aldo feel that larger valves and pocket porting the heads are a waste of money. Do you have any experience with the Subaru turbo charged engines?
Yes it far from a bad head IF you know what you are doing - though it is not the easiest to do.

YeeeeHaaaaw!!!! 👍👍😎
Thanks!
Doesn't matter how much the heads flow if it's got the "wrong cam" timing and valve events...
I've got a feeling dv and Richard are going to have discussions over camshaft timing
Nice observation, Einstein.....👀. Someone who has developed cam spec software is more than aware of that without your input!
@@trailerparkcryptoking5213 I take it you've seen Richard degree a cam before. I have never once. David's porting the heads for Richard... I'd assume he not assembling the engine. But perhaps you know more than I do.
@@trailerparkcryptoking5213 oh I don't doubt David vizard I guess that went over your head
@@mcintyretyler89 besides you’re shitty grammar you also make assumptions! 🤡🤣🤡
👍💪
Dave? Funny, our IH Comanche SV big blocks, all have 45 degree valves except the 392 has a 30 degree intake, what are the sealing issues????? Im watching you trying to learn and crack the code on these heads, they come stock with the intakes ports and bowls like race heads, but the exhaust bowls are just flat out wonky !!!!! Your contact email failed, I want to mold my ports and send them to you, with out porting they fall flat at 5,000 rpm with any cam you stick in it......
im going to guess the seat seal issue is only w/o lead?
No!

Hello frend. We meet again
@@mcintyretyler89 Gidday, Mate ! Might be in town for a Coupla days🫡
Bing bong
I gave the 400th like, what do I win? 😉
Is this a fake David Vizard channel? Looks like somebody is copying and reposting all of David videos
David needed to reboot his channel due to Marvin passing.
@@servediocylinderheads so is this the real David, Or is this a fake account stealing his content?
It's really him, he had to launch another channel after Marvin passed because he had all of the credentials.
Bath tub chambers, an exercise in lazy production engineering.
I thought that my PS2 was booting up at first
DV, Thanks. v/r wh
