WITH COPPERyou have the ability to use single gaskets in various thicknesses AND you can even stack them. When used in combination with copper barrel to block gaskets there are many dimensional combinations at your disposal. You are able to zero in precisely on the clearance numbers you need!
THE THICKNESSES AVAILABLE in head gaskets are .022, .032 (stock), .042, .052.
Copper barrel to block gaskets are available in .012 (stock), .022 and .032.
Although it's generally thought that you can stack up to 3 gaskets at a time. We never liked doing that and that's why we offer such a wide range of thicknesses all the way up to .062. We recommend up to two at the head gasket and two at the block end. You could pick up around .180 that way (A situation that you would probably never encounter)
we are also offering an extra thin
head gasket at .022. Normally you would not want to raise your compression ratio - but there
some situations where you may want to. We've been asked for them so here they are.
IMPORTANT -It's important that all surfaces be in good condition especially with the .022 thick gaskets. This is obviously good practice with any head gasket, copper or steel.
It's a good idea to coat copper (and steel) head gaskets with anti-seize upon installation.
