Jason:
I ported a set of turbo 301 heads, for a buddy of mine's N/A 301-powered 4-door '80 Bonneville. I must say: I have yet to see a set of heads with less counter-productive intake and exhaust port characteristics; nevermind the sizing of the intake and exhaust valves. I must have done something right, though, b/c even with a very mild Comp Cams grind and a VERY mild powertrain setup: The darned thing runs 14.4's; LOL.
