That's mad! I literally just spent a long time doing my vvti ge head. Lots of little differences between the vvti and non vvti ge! Main thing off the bat, is the port divider seems way longer on the non vvti. Exhaust looks similar But I did it the long way by using different sized balls as a guide for each throat..(I'm a noob here..) Love the channel! Dave. PS.. also wedged 2 welding rods on a flap wheel to gauge the port entry angle vs the turbo head..not only is is raised up a bunch, it's got a nice upward angle and taper..where as the turbo is almost 90 degrees to the deck Such a better starting point. Why they aren't used more is a mystery point
good advice ,cool video! the only thing I do different is I don't touch the elevator in front of the valve guides, I also do not touch the lip which separates the two valve conduits, so that it is, the effect of an airplane wing, if we make it pointed we create a lot of turbulence on the sharp edge like a blade .Great! sorry for langage i'm in France .
So ive been Told by a few People that you want the Intake Ports to actually be a little rough because it helps mix and Atomize the A/F Mixture... Is there any Truth to that?
Ok, thanks. I'll repeat my question here about the previous video about 1300hp 4g63 head. It did not look like it eas ported by you previously. At least the combustion chamber. Did you port it or someone else?
Highyly enjoying all the detail you show with the head porting! Thanks for the great video 🔥
Very welcome!
5:36 and 6:10
I've never had the balls to pass a spinning burr thru a valve seat.
What a boss!
I noticed that too and was thinking OMG!! What a boss indeed!
Great, now I gotta wait for part 2 to see the numbers. Great video David, always anxious to see the 2jz head videos.
Definitely learning from this. Appreciate the knowledge
Thanks for sharing, nice presentation and knowledge here💯
Thanks!
🇦🇬
Looking forward to Part 2. ⭐️⭐️⭐️⭐️⭐️.

For a newbie I like your ideas in keeping it consistent! Thanks for sharing and the kind words!
@@headgames I seen the video pop up and I'm like, oh oh..how bad did I mess it up..😅
Thanks for video!

Thanks, Dave. If it was at 86% already, what was the target %?
Great video would you be willing to do the Australian ford Barra 6 cylinder head?
No sir. Not enough demand for us to do the R&D

Yeah, we do not go any smoother than 60 grit
@@headgames Gotcha.
What's the point of commenting if you dont reply..?
I try to reply to all of them. Unfortunately, I’m still human.

It was our cnc port with cnc chambers.
