Wtb L28 1mm Headgasket

Seeing I've got the head off at the moment, might be a good time to go to a 1mm gasket and up the compression a bit. Trouble is other than a Kameri item (japan via usa!) I'm having trouble hunting one down. Any ideas? Apparently Fel-pro do one, but there website is pretty vague.

I had a gasket made for an import G180Z Isuzu engine (jap Gemini) and it wasn't that expensive, but I can't remember the name of the company pretty sure they were in VIC, somewhere. Might be worth a try googling?

The increased performance provided by reducing the gasket from 7.1cc's to 5.7cc's (standard vs. Felpro/HKS 1mm) could be far outweighed by the cost of getting hold of one!

You'll probably get more performance from the car by removing the spare tyre.

Just my 2c worth...

bummer... you'd think there'd be enough of a market that there would be more of them around at a reasonable price. I do like the sound of having a hardy copper gasket made, if it's not horribly expensive.

The reason Im interested in all this is I had a play with the old Lengine calculator and it recons Im only making about 9.8 to 1 compression, which isn't exactly mind-blowing. Has anyone played about with machining the heads and using shims to avoid valve clearance problems? Or is this path also wasting a lot of cash for a nominal amount of additional compression?
