You "could" keep the headers you have and get a V8 swap going to hook them to. :-k :-k :yawinkle:

I think I'm sticking with the 4.3 untill it needs to be replaced, it would be near impossible to do a V8 swap for quite some time unless I paid someone to do it for me.

Was it Mesa "performance/tuning/go-fast/whatever" that made the only true headers for Astro/Safaris?

I just did some digging around, "97TurboAstro" had Mesa stainless headers, but Mesa is no longer in business.

Heres his turbo build, http://gregoryusa.net/astro/turbo/

Does anyone know if this guy still has the few extra sets of headers he mentioned, or if anyone else has them to sell? That would be awsome if they were still available
