i saw that...and have seen other intakes, but haven't ever seen a set of heads for sale..
btw, before someone chimes in, i want these for my rodded 68 c-10, not my 4x, as from what i understand they are for higher rpms
when they 1st came out, i read that the heads were for nascar teams to use production shortblocks and bolt these heads on and bump compression to 15:1, to use the fact that production shortblocks would stand up to the abuse as a selling point
so i would use dished pistons to get about 11.5/12:1 compression for the strip, i believe these were the 1st mirror port heads gm ever made.
4x4high...i know you know your stuff, in your opinion, what heads would be close to the sb2 equals and good for a hi-rpm strip motor?
