hey guys, just wondering what you would suggest for an M6 to make the best power and also just as important good power under the curve. i dont want a peaky motor, i am really looking for something that is well rounded. lets hear your opinions on the best heads and cam for the street to make over 525 crank horsepower. this is the set up the car has right now (never dynoed, never ran at track)

Agostino Heads 296cfm @ .600 intake & 234 @ .600, Comp Cam XE-R 236/236 @.50 .602/.602 @.50 110LS, LS6 Intake, Ported TB, 30lb inj, Whisper Lid, Fast Toys Ramair, March underdrive pullies, Comp R lifters, Flowtech Longtubes, X-Pipe, Dynomax bullets dump @ axle with cutouts stock 3.42s

i know this is a pretty stout motor but i just feel there could be room for some slight improvements. for example i think i could get some better flowing heads. what do you guys think this thing would dyno? i would LOVE to make 440 rwhp and tq from a 346 on pump gas, is that within reach?

Alot of your hp expectations are going to be had by the tune on the car.

As far as changing the cam, run the car 1st before deciding you need something bigger, who knows maybe your makin 440 now.

i dont know those heads but you could most likely pick up 10 to 15 at the wheels with a fast 90/90. most people making 440+ are running an aftermarket head like afr, tfs, etp, dart etc. also is the car a4 or m6?
