Im thinking maybe the combination of the standard arp's and the cometic may be the weak leak.

I know I'm a DSM guy, but..

There is nothing worse than completing a big buildup, and having a car push coolant.

My advice would be o-ringing either the head or the block (Shep did my head, great job) and GOOD head studs.

More than likely the good head studs are not necessary with an oringed surface, unless you are pushing massive boost, but they are good insurance.

Just a reminder that you won't really have a band-aid at this point if your tune is off, so be sure to trust your tuner and your setup.

Ya its true!! Pushing coolant does suck! But i definatly trust the tuner completly he and I have been working with each other for over 2 years and he does an awesome job! -THANKS LUCAS GAINES-

Waiting to get some funds put together. Hoping to get it done for nopi Colorado in june so definatly crossing fingers..
