i did an arp head stud upgrade for the turbo teg a while back, people were telling me go with oem head gasket cause i was only doing 7 psi. the thing i realize was the torque specs for the arp are much more than stock studs and this is an oem gasket, since then there has always been a slight oil leak between the head and block, it's also leaking from else where like the cam seal. i've been itching to replace it with a cometic this time but have any of you guys have the same problem with arp on oem hg? (also fixing other leaks) also where can i get a good deal on a 81mm cometic head gasket or a kit?

 

is there a break in period necessary? cause i just kinda took it for a beating....

 

i had my head and block both resurfaced, cometic hg with copper spray and ARP headstuds and i have never had a leak, and no there is no break in period.

question though, do you have any sort of crankcase ventilation? Sometime crankcase pressure shoots up and causes loads of leaks...

 

that's what im going to add with the cometic h.g. when i do, a breather kid in the back of the block.
