    silverado ss heads

    well, the truck has a vortec 6.0 in it.

    what stamp heads are on these trucks? I think it would have been way cooler if GM put a LS2 in these things! they put it in the damn trailblazer!

    317 heads. They have the exact same ports as the ls2 and ls6 917's and 243's but with 70cc chambers I believe. They have the same cam as the '01-'02 ls1. You can make all the power of an ls2 with one
