Re: Cylinder heads. Stock iron or aluminum?
FWIW, my point was that you can put a set of alum. heads on the car and see a big improvement of even a set of ported stock heads. I have a set of ported 66 289 heads, 1.94/1.50 valves etc, and they still dont flow as good as any alum. head out there. Just remember to get pistons with notches to match whatever head you use.
