Re: 4.8L heads/how much h.p Ported heads are typically 30 to 50 hp depending on port flow and compression gains.Ls6 intake may be worth 10 to 20 hp if your combo is relying on its extra volume and flow.This question cant be answered accurately without important specs and details included. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
