Hey, I have a 2000 Cummins see sign. Been running 46psi for nearly 1,5years and now the gasket leaks in front, oil coming out.No studs std headgasket.Just over torqued std bolts.
So need advice. Should i fire ring it , O-ring it.Or just get a cometic head gasket, or marine head gasket or std Cummins headgasket??Getting studs now.
May doo twins in future and a cam.
Truck is a DD.What is reccomended for a DD running max 60 psi twins?
Running smarty ADR stack

 

I run a standard cummins head gasket with ARP studs @ 135lbs/ft and push 75psi when I really get into the throttle with my twins.

it's a daily driver as well

 

ever heard of anyone running a he351 with an 80mm on a 12v? im thinking of doing this

 

sounds like a drive pressure disaster waiting to happen...

better off with a 75mm with a he351

smallest turbo I would run with a S480 would be a 62/71/14

and that would have to be on a setup where you plan to exceed 750hp

 

Ya I scraped that idea and went with a 75mm

 

Hey...man o man... some head gaskets go at 40 others hold past 80. whos knows! Did you see this? Really god info here:
