Anyway, I screwed up this head. It's a real shame. It was going great, but I went too far on the floor like a dummy.

Hello jhowell

It's more effective to blow air through a port. You just have to increase the pressure. No problem with a turbo.
Sucking air through a port is something different. You only have 1 bar to work with, before you create a total vacuum. Total vacuum = no air/o2

Noah,
get out your reading glasses and start in 2008 for lots and lots of interesting info.

I remember seeing a thread a few years ago with some hand drawn images of what head work should be done. I think it was on RL (maybe in the turbo forum?).

Anyone else remember it?
