So we all know there is endless threads for 3mm headgaskets but I'm curious about the 2mm before I possibly go back to an oem HG.

If you have a 2mm can you list:

How many miles:
Fuel/meth:
Turbo/manifold:
Boost:
Whp:
Engine:
Any additional information:

 

How many miles: 80K (20K boosted on 2mm gasket)
Fuel/meth: 91 Oct + 15% Meth
Turbo/manifold: GT3567R / Full-Race
Boost: 19 PSI
Whp: 507whp
Engine: F20C
Any additional information: ARP Head Studs

I think a 2mm is great! I've never had any problems with my gasket. Got it straight through cometic, Checked the gasket for any burrs or imperfections. I think you won't have any problems with a 2mm gasket.

 

I suggest if you run the 2mm, use new stock head bolts. But running the 1mm with stock head bolts would be even better. Just make sure your tuner has a clue.

everyone seemed to have issues with the 3mm so I went with the 2mm cometic and sprayed both sides with copper head gasket spray. Works awesome so far no problems at all.

I ran the cometic and it lasted about 3 months before it started leaking between cylinders 2&3 at 413whp. i will never use a HG other than oem ever again and i will never install one on a friends car out of respect.
