Okay I bought a speed inc SI7 cam this last week and need a great set of heads to help this cam breath.... I have looked at all the different heads and cant make up my mind... I really like the idea of running a set of mast motorsports rectangular small bore heads on my ls1...

Engine is a forged iron 347.... -4cc Diamond pistons/ eagle h-beams/ Stock crank

cam specs 238/244 .605/.612 110lsa
