Not really wanting to change it just didn't know if this would really hurt with auto vs m6 that's all and it's more of a weekend type Car. The car made just under 500n/a on a loaded dyno as is with m6. Just didn't know if anyone knew or had a better option or would this work fine

Your number sounds a little high on ls1 power most I have seen with afr heads and a pat g cam was 460-470rwhp with out dropping a **** tinning money them . Keep in mind I amnon a mustang dyno which reads 6% lower and I have unported stock heads and intake and my numbers are with avg amount if timing, we added more timin and kept pickin up more. every degree added 8 rwhp even past 30* so I know I need heads and intake I should be around 550ish.

110 all the time as I stated my heads are hurting me quite a bit and was that a dyno jet saw corrected what was temp outside etc all has plays a factor. My session no fan 110* shop temp 10% humidity. so ya my numbers aren't crazy high but there ok considering conditions and under 3k in the engine just saying nothing crazy and I know the numbers would be higher today's 50* weather

Just spoke with pat g and he said that its damn good power on a honest dyno with stock ls3 top end on a 6.0 and he would just do heads. Said cams bigger than he would recommend do to street manners but if I can live with that dont change it

I'd have the ls3's ported as well as the intake. If you change to cathedral heads, factor in a fast intake or something similar. That drives the cost up as well.
If you stick with the ls3 setup, call Geoff@eps. He seems to have the ls3 style cam profiles nailed down pretty good.
