I would like to run vortec heads on a 383 in my 72 3/4ton 4x4 with camper. But I am conserned that with out a heat cross over it may not work well. Your thoughts?

Thanks

The crossover heat thing doesn't mean any thing, carry on!!!!!!!!!

Like Chris say, the heat crossover is not an issue - in fact, I think it was originally intended to provide a heat source for the choke assembly coil on stock carbs...

Thanks guys. I will get the heads,intake and rocker arms etc. Hoping for about 375hp and 425tq with smooth idle cam. Sound about right? Thanks.
