do heads without cam? im still debating doing a cam but i was thinking about doin some patriot stage 2 heads. i want to hit 400 rwhp and i will have every bolt on from the EWP, entire intake and exhaust with a cut out too. figure heads might beable to get me there....maybe.....thinking the 5.3L heads or the LS6 heads. any opinions? could i get to 400? i mean i wanna do a cam in the future just not yet...
So tell us what cam are you thinking about?

honestly i dont knwo what kinda cam i want, dont know much about them. but from what i read i want to get something along the lines of a 224 with about .580 lift or so, but hell i really dont know what would be good but i dont wanna go too extreme. would i benefit from getting better flowing heads. i dont know how long it will be before i get a cam really. im really wanting to hit the 400 RWHP mark. can i just do heads? leaving the cam out of it for now, i want opinions on both and then ill go from there, so what heads to get without a cam and what heads to get with a cam around those specs

with stock gears and all the bolt ons you can get right at 400 on stock heads and a 224 cam with a 112lsa. and save the 2k+ for a rear and gears which for now is worth much more imo. especially with a 400hp m6. and gears are worth more in the quarter than heads.

ported heads and a stock cam are a waste. your better off with bolt ons, new cam, and stock heads. whats the point of ported ls6 heads that flow 300cfm@600 with a stock cam that'll still peaks at about 5500 rpm or so. a cam swap is very easy, and you can experiment with different ones quite simply before looking into heads.

as far as cam for a daily driver i'd stick with 224 on the 112. if you want more lift go with the comp grind that has .581 lift over the thunders .563.

Sure, you can do the heads but don't expect the world. You'll only really be able to use them to their potential after a cam swap, of course. This is not normal practice, however, because an aftermarket cam will net the highest gains just by leaving the stock heads on.
