stock headers
I'm fixing to rid my 86 IROC of its 305 and get me a 350 tpi. My question is, will the stock headers bolt up to the new 350? I probably won't have enough for new headers after buying and installing the engine.

Ok, sorry, i meant manifold. So all i gotta do, take out my 305, put in 350 and everything should bolt up exhaust wise? Probably should move this to engine swap....

Yep, but this is a good time to put headers on so you can save a little hassle later.. Of course money permitting.

you have manifolds stock, headers are tubular. Yes they will bolt up. 305 TPI should have the same manifolds as a 350 TPI.
