Hey I know someone that has some L98 heads that they are giving away.. there completely bare tho. So my question is, will there be a worthy power gain from the swap or is it not worth the trouble? And about how much would it run for valves, springs etc? or will the ones on my heads now work with these?

 

corvette L98 aluminum or f body "L98"?

 

Not sure but I would assume the later.. seeing as that there free and all

 

Not worth it, your compression ratio will go down a lot and will negate any gains from the extra flow.

 

Thats what I was thinking, but just wanted to make sure - Thanks!

 

There is a drop in compression but the heads are still superior to that of the stockers. I would still use them and live with the CR drop. Not ideal but better. You could get them shaved and use a thinner head gasket as well if you have the funds. Your efforts will be pointless though unless you go with a better cam.
