oem headbolts

[johnny_k]

Are oem headbolts ok for a tdo4 at 1.4 bar? or would you need arp bolts? also is the athena 1.2mm headgasket ok for 1.4 bar?

Thanks
John

Athena gasket will be fine, the OE bolts should also be fine but for peace of mind I would always recommend ARP.

I used to run 1.6 bar on standard headbolts, it was fine but that was before arp's were available, like Mike says arp's just to be safe
