Inliners International Forums General Discussion Blown and Injected Hacking together EFI on an Pontiac OHC Six

I understand.
You could still back cut the valves if they do not have any.

Should not effect the valve height.

I was noticing the turbo head you posted earlier pics of.
From the pic it looks like the guy only opened up the chamber on the long turn side, not the short turn radius side.
