lifting heads How much boost can you run on Patroit head befor you should have trouble with heads lifiting? I am currently running 10 to 12psi. I have setup in sig and am currently having trouble with pushing water and leaking around heads. I have ARP 12 point headstuds tq to spec. Will the Patroit heads just not hold because not as thick of deck hickness or what do you all think? I am using the factory MLS 6.0 gasket.

We run the Patriot heads at 16 psi of boost. This C5 is being run hard on a road course with Patriot Stage 2 heads at 740 rwhp. http://www.exoticperformanceplus.com...Car.php?car=40 Bob

anyone else think that the torque/HG might have somthing to do with it?
i have heard that it is best to go around torquing in increments of 5lbs, torque, then retorque at final ft/lbs.

I run mine all the time between 14-16 on pump gas and 20 on race gas....
I pushed a Lil bit of water on my last pass at the track... after 4 passes.... it was just a lil bit....
Nothing im worried about because ive been told by the people who done this before me that its going to happen sooner or later and i need to keep checking it and add water as needed........
If/When i blow a head gasket i plan on O-Ringing the heads....
Ill be pushing more then 20 psi next tiem out for sure......
My heads were Patriots to begin with but i had to have them gone thru... so there no longer Patriots....
