What heads will fit on a 87 iroc
Its been a few years since i've played around with the 3rd gen's.Will older style heads fit on this engine or do they have to be 1987 and up style?

Any SBC heads will fit inc Vortec ( requires special Vortec intake )
Late F-Body intakes and heads such as a 87 engine have the 72 degree bolt angle on the center 4 bolts ;
where as reg SBC head have 90 degree on all 6 bolts
so head choice determined by intake style
