i have been looking at new heads, all i have on my truck is straight pipes, a cai, and a custom tune..

im looking at right now getting some heads, and a cam.

i want heads with really good power gains.. i dont plan on supercharging or turbo'ing.. i just want it to haul *** off engine.

what do you guys think about these heads?
Lingenfelter CNC Ported Aluminum 5.3 L Cylinder Heads -Pair - Lingenfelter Performance

and would i need anything else with them? post me some links to some other heads if they are better or i should go that route.

also for a cam, ive been looking at the tsp224r, and the tr224..
I always see ls1 cams being talked about on the internet..
i just want some power gains from it. i also want it to sound pretty nasty, have some lope to it but not lose power..

Im not an expert on this stuff. Im more of an electronics guy. So just gimme suggestions or advice about what i listed, or about some cams and heads. thank yall.
