dude

normal head gaskets have metal rings around the holes for the pistons to help with compression. i have nevwer heard of someone making a headgasket b4.
you still need to have the right material as it compresses when head bolts are done up.

better off buying one as a home made one probally wont last and do more damage than good.


but this is only a suggestion.

you could go to repco and ask to have a look at there headgasket kit and ask to measure it.

If the gasket is made of anneled copper or similar I reckon it would work fine. Sorry I have no idea of the head gasket thickness when compressed.

I could be totally wrong but once before i was told that with L series motors you can get different thickness headgaskets for them depending on what markings they have somewhere on the head somewhere.

IM not 100 % sure on this, but have made copper head gaskets before and when i made it (was for a motor bike, about 12 years ago) I was advised to heat the gasket up very hot. but i cant remember if it was then just allowed to cool or if it was cooled quickly in water.

As i said im not 100% on it but i think it had something to do with the softness of the copper gasket.

is a aftermarket head gasket very expensive?

You quench it quick and that anneals the copper, and makes it soft.

My 2 cents worth is this...on a diesel, the thickness gasket depended on how far the crown of the piston protruded out the top of the block.
I dont think you need to touch the gasket when adding a turbo... unlike a petrol motor that sometimes you need to decompress...remember...your cam is belt driven and the further away from the crank the head is, themore advanced the cam will be.
