Opinions on Heads and Cam for LS2 What kind of power and idle quality should I expect from the following combo? Any alternate suggestions would be appreciated.
AFR Mongoose Heads: 205cc Intake Ports, 66cc chamber, 3 angle grind, 2.02/1.60 valves. 300 cfm @ .600 lift
Comp Cams Energy Extreme: Hydraulic Roller, .580x.590, 114 degree, (@.050in)…230 deg in/232 deg exh duration
Stock Compression: 11:1
Stock Manifold
Upgraded injectors to 30 or 40 lbs.
A couple people I've talked to mentioned using Ford red top or green top injectors. Mainly for the price, but I can't find any info on whether they will actually work on an LS2. Any suggestions?
Thanks, Mike

wrong section. Mods?
But...
Are you asking wheel hp, fly hp, or engine hp on a dyno?
That's a pretty mild cam and heads for an LS2. Not that there's anything wrong with that; just an observation.
I'm going to use th '04 GTO as a base reference. It was rated at 350 HP at the fly, so we'll assume that's the same measurement you'll be using. With the current combo, I would think that 385-400 Fly HP is reasonable.
However, for more power, you could definitely switch to a more aggressive cam.

With that, I bet you could gain another 50-60HP, so something like 440-450. That might be generous though. Anybody else??
Side note: I don't know if you're using a T56, but it's factory rated at 450HP. Be careful you don't overload the tranny in any case.
