Head gasket recommendations

[Josho Mate Theurillat]

Im trying to decide what head gasket i should use for my 6bolt 4g63.

I have arp studs and am running 23 pounds of boost the head has been skimmed but the block hasn't.

Previous head gasket was a "monotorque" brand

Most would say oem mitsu.
I would go oem mitsu =)
Or
Hks.

Go for a grommet or fire ring style. Where the cylinder is sealed with a rolled lip and not exposed to the multilayer sheets. The multilayer sheets expose the risk of a leak.

Is a oem mitsubishi head gasket mls? Also when ordering how do i know how to get the right size for my bores? One piston has 0.50 stamped on it or it might be .050 ill have to double check that

I am currently going back to Copper Head Gaskets, On a certain Starion it's the only thing that has kept together. This enigine is running 30PSI for 30min Sessions. The MLS Gaskets Cometic, HKS & OEM failed. I now have 3 Copper units on the shelf for engines I build.
