diesel pap,

ive got the setup in my sig and dont have a blown headgasket or anything but would like the extra security of your bolts if they truly have more clamping force than stock bolts do. how much boost and or backpressure would you recomend going up to with your allen head bolts?

 

my mech buddy says 70 lb and never look back although he has seen alot higher with no problems.

but remember you have to have a flat head. he does them alot 1 at a time but you are really taking a slight risk not knowing how flat your head is.

i am going to have a set put in my 6.7 1 at a time

 

stick with a stock gasket, get 60lb springs, o-ring it, and studs do a few re-torques and call it good

 

yeah i need orings soon too

 

Imo from what I know now, 60lb springs are a waste of time. The only time I would recommend them is for an exhaust brake.

 

Hey Diesel Pap,

I've got your head bolts. I plan on running 45-50 psi, but I'm likely to spray it too. I can tell those bolts have a lot higher clamping force than stock, but I'm not sure they have that much. Has anybody your way got any experience with that?

 

they spray all the time

they have been tested many times
