I'm currently rebuilding the engine in my 68 Pontiac Firebird. The car has been in my family since 1972. My grandfather purchased it from his boss who purchase it new. It's mostly original with 68K miles and numbers matching. It's a 320 HP 350 H.O. with 4-speed car. I'm thinking about upgrading the exhaust manifolds. I don't want to go with header if possible. I'm thinking about installing a set of Ram Air III manifolds. I found a set on Ebay, but they're for 68 and 69 GTO. Does anyone know if these will work on a Firebird without issues?

Thanks,
