head gaskets l92 Does anyone know what the minimum bore diameter head gasket can be run with l92 heads on an ls2 without having any of the fire ring protruding into the combustion chamber. The combustion chambers are unported. Any help on this would be greatly appreciated.

Correct, we recommend a 4.085" bore gasket (or greater in some cases depending on the bottom end as well).

I believe the reason is to prevent the gasket from hangin out into the large chambers which can cause gasket failure and shrouding of the valves.
Even if you are running a 4.0 bore you will need to use the 6.2 gaskets
(4.085) just to be safe.

Along with larger gaskets what is the number for replacement head bolts or studs ARP? Are you using stock length push rods also? Thanks (I just got my L92 heads & have Manley valves for them & retainers (ti). Trying to get all the things together like head gaskets & etc.
