I have some 241, 862, and 706 heads available for a decent price. Would the 241 LS1 heads be more desirable than the 706 and 862 5.3 truck heads?

So if i decided to go with the 243 heads or perhaps the 241 heads, would i need a different intake manifold and/or any other parts? or can i use all my stock 5.3 stuff?

Stock 5.3 intake would work.

So it appears that there are two different types of 243 heads, the ls2 heads and the ls6 heads. Is it really worth it for this build to get the ls6 heads over the ls2 heads?

They flow the same, just different springs IIRC.

243 heads have two different setups, one setup from the corvette LS6 will have sodium filled exhaust valves and the 243 heads from all other vehicles have the old standard plain valves.

Thats what it was, the valves.
