Exhaust Manifolds

ibkg · 09-07-2008, 11:47 AM

I have a 1984 C 30 2wd 4speed 350 engine one of my heads had a burnt valve my original heads were 093 with 7 bolt exhaust manifolds where the exhaust manifold was above the plugs so I found a set of redone 882 heads and installed them the only thing they have 6 bolt exhaust manifolds and my original manifolds won't bolt up anymore my question is will a set of exhaust manifolds from a truck in the 70's where the exhaust manifold went under the plugs work? I sure appreciate any help on this thanks. KG

Welcome to the site
If you use them you will probably find the crossover won't fit. Find a decent set of headers and build from there.
Or rebuild your original heads

Thanks for the welcome I have a set of headers but really don't want to use them I'd rather go with regular manifolds I know the y pipe would have to be changed just wondered if a older set of manifolds would work I already have the 882 heads on and the truck running just no exhaust thanks for your help

As long as the port size is the same they will work, manifolds off a 262 had smaller ports but would bolt up. If they are off a 350 they will work
