487X heads
Hey guys I was wondering of these heads would be a good replacement for my stock L98 heads for my TBI 350, and also what kind of performance gains (if any) would I expect to see?

Sounds like just yerbasic 2bbl bread-and-butter car heads to me. I'd pass on them.

I have an L98 im swapping in, the L03 is in the car for now, just wondering if i should keep the heads or not for the 350
I actually heard somewhere that the 305 HO heads put on a 350 would do some good, any thoughts? (I have a pair laying around)
