Hello, I have been looking into either 12mm or 14mm head studs and fireringed cylinder head has anyone blown a headgasket using the smaller studs ?? I was to hrvp, 150 injectors, smarty and a comp would blow my new gasket and also was told if i put on my Ind Inj sb that i would pobably destroy the head when the gasket lets go. I havnt found many failed gasket issues with studs during a search but any info would be great.

 

I have the smaller studs in my truck for about a year and havent' had any problems ... yet. Its also fireringed. I also run the silverbullet and hit 60# all the time

 

I've been running 40+psi of boost, TST, Smarty, bd155's for over a year now with no headgasket issues. I just installed the 12mm studs and I'm spraying water/meth and knock on wood I haven't had any issues. I've got 125k miles on the stock headgasket. The 12mm studs will be fine for anything under 1000hp. With studs and fire rings I wouldn't worry about anything else at all. I'd spray nitrous, water/meth, run lots of timing, etc.

 

thats kind of what i thought, i dont think i even make 400 hp let alone a 1000 hp, thanks

 

anybody else ??

 

I made just shy of 450rwhp at 42psi on an HX40... the head gasket finally let go at about 250k miles... that was 100% stock gasket/bolts/etc.

 

Plenty of times. I am tapping my block RIGHT NOW. Just taking a break for a minute. If I could go back I would do without the firerings and just use studs alone...
