Re: 6.0 CI Head Flow Numbers This question is probably better suited to the internal engine section even though they're truck heads. 
I'll move a copy of it over there.

Re: 6.0 CI Head Flow Numbers You looking for stock head flow numbers or ported? Your best bet is in the internal engine section.
I used a set of ARE stage 2 6Ls that flowed 295 intake and 220 exhaust I think.

Re: 6.0 CI Head Flow Numbers Mine were flowed at 295 intake and 245 exhasut, 2.020" 1.60" valves
they are at the shop getting fitted for big springs and 2.055 intake valves. Will be re-flowed after that is done.

Re: 6.0 CI Head Flow Numbers AAP is "supposedly" pushing out a 330+ CFM head. i dont see why this wouldnt be possible, but why not start looking C5R? compression concerns?

Re: 6.0 CI Head Flow Numbers
I have a set flowed at 320 & 242 with 2.08 and 1.60's.
We can get 330+ for big inch motors. C5R is just way to large for a street car, you loose all volocity and lowend.
Re: 6.0 CI Head Flow Numbers AAP is Andys Auto Perfromance, they were a sponsor until the owner Mark Avila was killed in a car accident 
. I have 5.7 AAP heads that flow 337 intake @ .600 and 242 exhaust. My buddy Micah has the 6.0 heads that flowed 342 cfm @. 600 on the intake, these heads were ported by Race Prep Race-Prep.com they know their **** and will soon be a sponsor on this stie. Good luck.

Re: 6.0 CI Head Flow Numbers Our Judson Massengill signature series heads are 100% CNC ported in house. They flow 330 cfm @ .600" and start at $1999 and go up to $2399 depending on which type of valve train components that are used, and the ports are high velocity small port volume. If you don't know who Judson is I met him two years ago here in Bowling Green, he won King of the Hill running 9.90's on motor, all the big guys were there, their power adder motors either broke or got beat. Pretty amazing to see a guy beat a bunch of LS1 and LT1 power adder cars on motor!
