e bay cylinder heads

Pro Comp is cast in China. That said, some of their heads are good, as in they work and can make more power that the stock factory iron head they are replacing. Buy them bare and buy quality hardware and have a reputable shop set them up. Like all, they respond to porting. But do your homework and see who is actually running them.

When doing homework for my dads 440 build, I looked into the Pro Comp B/RB head and what I found was they are a copy of the Edelbrock Victor Head, meaning they require offset rockers and I think headers to clear an angled spark plug. We ended up using 915 heads.
