5.3 Heads? Ive been thinking of getting some 5.3 heads and was wondering if they would flow ok on a LS1 motor or would I have to get them P&P'ed so they would flow enough for the block?

stock 5.3 heads use a 1.89" intake valve and have a smaller combustion chamber but flow on par stock for stock with an ls1 head. With the abundance of sub 1k cylinder heads its easier and better to just purchase a set of already ported 5.3's or a set of ls6 heads ported.
