Big block swap headers

I have installed a big block chevy into a 92 firebird and have seen where guys have used a header that was not specific for this swap ! I really don't want to shell out 500 , on a budget you know ! I have heard that there is a header that that I can purchase for a big block that will work but I can't remember for what car , thanks guys !

I've got a set I used for a year. I ended up buying the $500 set. If your interested, I'll find a pic and post it.

Re: Big block swap headers

That thread on the Patriots shows exactly how to make them fit. They're good quality for right around $200. If I was ranking by price, it would be manifolds then Patriots then Hookers then Lemons. If rating by power potential, then reverse that list, unless you're adding twin turbos, in which case EBay has stainless forward-dump headers for under $200
