will these heads fit my 89 iroc 350 Tpi?
Hello
These are a set of L98 corvette heads [aluminum]. They are the centerbolt style but i dont know for sure if they wil fit and i wanted confirmation. Apartently he claims they fit 87-92 but i need to be sure that they will fit my 1989 350 TPI.
Thanks

i dont know anything about casting numbers on these heads but here it is
14101128
They are 58cc by the way. I have heard that the 113 heads are the desirable ones, what is the difference between these and those?

Aluminum, 58cc, angle plug, raised

Aluminum, 58cc, angle plug
The 113's are newer, so I guess the raised D port exhaust was a provision for better flow

Do a search for "L98 aluminum heads" or "Corvette heads" and you'll find all the info you want. There are a couple problems with them, including the intake bolts, accessory bolts, and no EGR.

he just told me that they were from an 88.
Sorry to bug but i dont know much about heads. Are these heads any better than my iroc L98 heads or is it a waste of money?
