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.thehanko wrote: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.

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.

blocks are often o-ringed when running copper headgaskets
