I'll be getting into this myself in the near future.
I have a head that was heavily shaved to bring compression up to near 11:1
on a race car
This head has been totally reworked with all the unleaded upgrades including
nice snap cap valve seals. Obviously I can't use it as is. I will be
purchasing a copper gasket to suite my needs of comp. reduction.
DOES ANYONE REMEMBER THE WEB SITE THAT SPECIALIZES IN THESE GASKETS?
(too many saved links to find it right now)
You can do all the normal calculations to figure compression.
Then just re-insert the values for the different thickness gasket volumes
and recalculate.
Even though you don't know the absolute numbers for your present motor,
.... you'll end up with a table of reference as
to the effect of the different thickness' on compression.

Subject: new copper headgasket
Because of the high compression, I plan to by a thicker cylinder had gasket.
I can buy them in the following thickness
.022,.032,.040,.043,.048".054,.063,.086, .093, and .125 inches.
125' is around 3mm, 0,093 is around 2,3mm and so on
Any idea how to find out how thick gasket I need ?
The guy who assembled the engine, adviced to use the thickes, because too
low compression is better than too high.
The block has been bored, at least once, probably twice.
Do I have to remove the top. and measure the exact diameter of the
cylinders, or just buy a 'standard'?
Thanks in advance
