Will L98 heads out of my 1990 5.7 Iroc fit on a 1988 L98 5.7 Iroc?

Your heads will fit any SBC, the intake is what you should worry about. 1987 (iron heads) and up use canted center bolts on the intake-to-head surface.

87-92 iron f-body L98 350 heads are all the same casting number, so yes you can use 1990 heads on a 1988.

The same with the 87-92 305 LB9 heads, they are all the same, too.

Yep, that's me. I take the 5 north to the 55 north every morning to work. I'm glad I'm not going south on the 55!!
