If they are stock LS6 heads I would consider that pretty good thru cats. What type of valve springs are you running? The graph takes a little dip there about 5800. Also do you know how much advance the cam has ground into it? If you have the cam card subtract the LSA from the ICL. A ported TB, and ASP pulley are good "dyno" mods.. along with some cutouts and and offroad pipes.

Change those springs to some 918's an you'll loose that dip in power at the top end. I bet you are getting a little valve float up there. Keep you eyes open in the classifieds and you can get some for around $75 sometimes.

Yeah, i wouldnt run that cam with yella terras and stock LS6 springs. Some 918's would probably be better.

400rwhp is only a cam swap away
