i have recently blown my JE Proseal Headgsket, looking for other alternative headgasket to run my 2.4L Long rod with 6466 PTE turbo

There are not many gaskets for 87.5mm piston. i can only find cometic and je proseal

 

Siruda makes 87.5mm in a variety of thicknesses

 

Cometic is good.

At the level youre at with the 6466, you really need to be thinking about oring'ing the head.

 

Cosmetics are for the ladies, I specifically use Cometic

Sorry Sean, couldnt resist

 

The cometic MLS ones are good? I torqued my L19 studs to 120ft ibs and with a machined flat head and deck..

 

Why are you over torquing the head studs?

 

whats the ideal torque for the L19s?

 

I torque L19's to 95 and have never had an issue.

For the custom AGE 625+ 11mm studs, ARP calls for 100ftlbs. And that's a WAY strong material than L19.
