Re: Heads and Intakes
The vortec heads are nice yes. I myself prefer World Heads. Larger valves, no messing with bolt patterns, ETC. Also, I've noticed that nobody here has talked about the EGR problem with swapping the vortec heads to an pre-96 350. They don't have the EGR ports in the heads, so you have to run a tube from one of the exhaust manifolds. Most all headers for the 88-95 trucks have a couple blockouts where you could fab one. I know my JBA's have 2. Also, look into swapping the Edelbrock Multiport injection. We did it for my friends 95 Z71, and power took off like a rocket. Mileage went up to about 20 on the highway, about 16 around town. You can do the multiport conversion, for the TBI computer, with the vortec heads, edelbrock sells the kit for doing just that. They also send a EGR with it. Those guys are way ahead of the game. The vortec heads are also a 64cc chamber, stock chevy heads are 76cc. So, plan on running super unleaded, or keeping your truck super cool. I put the World Torquer heads on my 94, and they are a big difference. They run about $650/pair, I bought mine from SDPC, Summit, Jegs, any aftermarket guy will sell them to you all day long. I've done alot of motor mods to my truck, some good, some bad. If you want the full list, let me know.
