1995 454 converstion to Vortec heads questions
Posted: Sat Jul 31, 2010 1:50 pm
Hi,
I've already searched through the posts, but still have some basic questions.
I have a 1995 K2500 truck with a TBI 454. (256k miles)
As you know, it has the "peanut" heads. I have a burned valve, and a couple broken exhaust studs from trying to replace the exhaust manifold gasket.
(which didn't happen)
Since I have to pull the heads, I'm putting a set from a 1998 truck (Vortec) heads on.
I want to get all the parts I need before I do this, as I need this truck.
I know I need a Vortec intake manifold, but the '96 and newer went multiport, so I guess if I want to use my TBI I have to buy a new Edelbrock.
>>Should I use the pushrods from the Vortec head motor or my original?
>>The exhaust manifolds look like the same bolt pattern, will they work?
Since i'm tearing it down, I'm going to replace the timing chain, and put in a new camshaft.
I use this truck for hauling a car, any recomendations (with the Vortec heads)....
Basically anyone who has done this or know of any issues, I sure do appreciate your time to reply.
