Shaved heads vs Power tune To start out with this motor is all stock. I am going to have the heads ported and the intake done for about a 6400 rpm limit. I thought about shaving the heads for about 11 to 1, will there be enough clearence for this? I want to run pump gas, will pump gas support 11to1...or will I have to detune for this? If I have to detune for it which is better leaving it stock 10.4 or shaving it?
the next question is about the cam selection....ported and polished heads for an rpm range to 6400rpm stock bottom end I do not want a stahl...weekend bracket racing and daily driving, headers and possibly changing from 3.23 to 3.42 or 3.73 gears my goal is mid 12's or possibly the 11's. I also have a zex wet kit to 125hp but I dont really want to use it. My conclusion is the hot cam kit... but is there anything bigger that dosn't need a stahl? Sorry for the rambling but there is a method to my madness. thanks.

Been there done a cam without gears and stall and after that experiance I am going to tell you don't bother especially with something as big as the HOT or larger. I did a ZZ4 cam which is 208/221 and gained almost nothing till I gave it stall, gears and headers.
Far as compression cam plays into it but MANY of us run 11.5-12.0 on 93 octane.
No need to shave the heads to get 11.0, the stock gasket is .049, Mr. Gasket offers one .026 which should be just about right to get you 11.0.
Also do not bother bumping compression without doing headers it can create detonation problems.
I am sure you expected to hear do the stall and gears and thought you knew more but listen to someone who tried what you are talking about when I say it is a mistake to try to do the cam without the other stuff. Cam only I gained almost nothing, gave it the stall and rebuilt tranny and dropped to 87 octane tuning from 93 and gained .8 in the quarter, gears(2.93 to 3.42) were another .2, headers were .7. More recently with the current heads and cam I swapped from the 3.42s to 3.73s and gained another .1.

You want a cam but not stall
What is your reason for this and why?? Who told you this a is a good idea?
I would do FULL BOTLONs and at least a GEAR!
I highly suggest going with a stall also, but you can live and learn

So how about this cc306..3.73gears...pacesetterLT...pcm4less tune...2500 to 2800 stahl...K n N cold air...11to1 with .026 gasket...ported and polish...with some sticky tires...what kind of power do you guys think, or possible quarter times? Did I forget anything? wont the cc306 be shifting higher than the 6400 safe point for the stock bottom end? thanks

I agree 100%. My car is a bolt-on motor with headers, 3200 stall, 3.73's. JUST with that alone im beating my buddys '02 trans am. And do at least a 3200 stall or better if you really want to turn some good 1/4 mile times. Im talking to my cam guy and hes saying to do 4.33's/4.56's with a 4k stall for my cam only car. Should put me in the low 11's.

You want to keep the revs low I would suggest something like the Crane 210/224, nearly everyone here will say it is too small BUT those who have tried it will rave about it. Also look at the little Lingenfelter cam 211/219.
