LS1 Z28 Heads?
Will a pair of ported LS1 heads off of a 1998 Z28 fit on a 97' C5?
Here are the flow #'s
Flow # are as follows. LIFT INT. EHX .100 65 55 .200 134 112 .300 205 151 .400 251 180 .500 275 200 .550 278 208 .550 282 212
They are 2.00/1.55 valve heads
Does this sound like a good deal if I can get them pretty cheap. They were ported and Polished by Lloyd Elliot in Texas(Speedtek)
Any advice would be appriciated Thanks MT

I know that pre 1999 F-body head have a different bolt pattern for the covers.
But I'm sure that with a pre 1999 vette the same holds true.
It could be for a 1997-98 Vette you need any corvette head, or 1999+ heads off an body. If nothing else, if the deal is really a steel, you can always buy new covers to fit. The heads themselves with bolt up no problem.

Yes they will fit no problem. the 97-98 Heads are exactly the same with a perimeter valve cover where the 99+ heads are exactly the same with a center bolt cover. The heads are absolute exactly the same whether from the f-body or corvtte and you can install 99+ heads on a 97-98 or visa versa with matching valve covers. I installed the 99+ heads on my 98 Z28 with center bolt valve covers, goodluck.
