Bigger Cam or LS6 Heads? What would put down more Hp? I was thinking about some stock heads but some guys say put in a bigger cam since it wont cost as much. Problem is I dont want to have to drop in a huge cam to make good power. I have 370rwhp and 354rwt right now but would like to see near 400. I also dont want to have to change gear ratio in this process. My car is a daily driver also. Thanks,

It depends. I think he meant stock ls6 heads. You can find those cores pretty cheap($500-600) on ebay sometimes. Those would be a great investment for the money, especially to use as cores down the road. They are something that will not likely lose their value if you go to sell them either. Most everyone will pay the half-cost of $600 for used ls6 heads as cores, instead of $1200 or $1300 charged by shops.
The cam, depending on whether you need springs or not, may net you more horses.....but you'll still need heads eventually
Plus, heads will pull a few more horses out of cams anyhow(more horses the bigger the cam).

I would think that you could put a good set of heads on your car and pick up 30 hp without sacrificing any driveability. There is nothing like having a 400hp car that idles dead stock.

Yup I mean putting on stock LS6 heads only because I got a good deal from a guy if I want them. Problem is I don't have the money to get them ported and polished and I'm married (married guys understand lol) so that's why it would have to be the stock heads. How much of a gain would I see just with the LS6 heads? Thanks,

Personally, Id just go with a different cam. it doesnt take a monster cam to make 400rwhp. My F11, w/ mac mids and usual bolt-ons in an automatic made near 390rwhp locked through a vig3200,stock rear w/3.42s. Think if i would've had LT hedders & a6sp i might wouldve hit over400+rwhp. F11 is not really a big cam(228/230 .581/.591) & it was very streetable IMHO. I think there are several cams out there that can get you 400+rwhp while still being quite streetable. Good luck w/ your decision and hope you meet your goals

For a couple hundred bucks you could get a slick valve job and a little short side radius work done and get some sweet numbers out of the 243's. It doesn't take much to get a 243 to flow 275 -300 cfm.
definitly go with heads as you already have a great cam. Find a great deal on some heads and slap them on there and wammy you will have over 400 rwhp and still use your gears! Won't be much more than a cam swap if you can find the ls6 heads somewhere for 600 bucks.
didnt know emmisions was a concern so ya id go with some LS6 patriot stage2 heads which are around $1400 assembled i believe or just get the factory LS6 heads. With a re-tune you should get your goal and more. Good luck Man
