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?
