I have a 71 chevy 1/2 ton with a 350 goodwrench crate. What I am wondering is if vortec heads from a 97 silverado will bolt up? i know i would need a new intake manifold. but they should work right?

I believe that they will...the exhaust is different too i thought...and i know vortec valve covers are center bolt...no bolts on the outside edges.

I have the valve covers from the vortec yet and im pretty sure the manifolds will fit because i currently have headers on it and they pass the frame with plenty of room...that is if the headers wont work yet. the only thing i dont know is the specs off my cam. im sure it doesnt have more than .470 lift which is the max for stock vortec springs. And im guessing i cant find those specs unless i take the cam out and measure it.
