They started putting those heads on newer trucks a couple years back. They will work just fine on your car.

I saw them on ebay. I haven't paid for nothing yet, I'm just looking right now. I'm planning on getting some Ls6 heads, Tr224 cam and a 3500 stall in about 3 weeks for my DD. I did some searching and read alot about DD with a 3500 stall and 224 cam. Am I missing anything....what about springs,lifters and pushrods. Car has 91k

DON'T get those ebay heads!

I just sent mine back. One of the two he sent me had chunks taken out of all major sealing surfaces. The replacement he sent had used (2 damaged) valves in the "new" head. Not the deal I thought they were. I bought the patriot spring kit to put in them so I was pretty much up to the same cost as the patriot heads.. now factor in machine work it wasn't worth it. I sent the heads back and will sell the spring kit and buy a nice set of heads.
