hmm i wonder the same thing. i would imagine so.. seems most mods do.. generally the bigger the cam the higher the rpm range.... but things like adding cubic inches increase tq down low...
one thing is for sure, those stage 2 ls6 heads would make more power everywhere on my car probably lol

Reason I ask is because I thought about going with a larger cam...but if these heads will really move my peak higher I won't want any more than the TR230 that I originally decided on. The combination of parts is key.

Gunnar, I really like the 2nd option from the top post. I have new in the box CC 921 springs. The bottom retainer is 1.30" in diameter, will this fit the heads OK? Since I allready have these springs, I want to use them.
I will call you tomorrow (Thursday). Can I get a bag of Super 7 locks?

Hey guys... I am somewhat new to ls1's.... i was previously turned off of patriot due to the options and info i saw in summitt comparing them to other vendors (cam choices suck) (... yet this sounds to good to be true)
59cc heads with new larger valves and high lift springs for less than 1400.00?? what is the compression ratio again with the bottom option for an ls1?
what cam will work well...... street cam, nice lope... not choppy idle, not a spring killer. looking for 400+whp on M6 with hooker LT's, H/C, and dumps. stock ls1 intake for now.

But with bigger valves, the way to do this is stick the cam in and measure PTV.
No sane sponsor here will give you a definite answer, it will be it "should" but "better measure", which is sound advice when you're playing with cams that size.
