Cometic High Compression Gasket
I've been in discussion with the folks at Cometic in regards to making a high compression gasket for our 4G69 motor. So far the conversations have been positive.
Lots of details on the power benefits of these gaskets can be found across the interwebs.
Lanzer is donating his extra OEM head gasket as template (thank you sir). Cometic will be using that as a template. Once they do their wizardy math hopefully we have a gasket that pushes us into the 10.2:1 CR and safely seals like the OEM gasket.
Stay tuned.

I do not know the thickness of the OEM MLS gasket yet. I've read anywhere from .030 to .051. The OEM head gasket is en route to Cometic tomorrow. Once they recieve it I will follow up with them for more prototyping discussions.

Crap,
I should up date this. Lanzer has shipped the gasket (with enough postage this time) off to Cometic. I will update once they've received. I would not be surprised if they require a group buy of some sort. Just want to set the proper expectation.
