reusable ,any thickness - 20 thou-1/8 inch.. allows you to salvage a badly warped head,or swap a 16 valve head and pistons into your sami or sidekick 8 valver without even removing the block from your rig,plus its a good excuse to take a look at whats in there, or whats not. reasonably priced--- $125.00 up to 1/8 inch. thinner is of course is cheaper. no more blown head gaskets.-sg

If your cyl. block has been O-ringed then I would say good, use them.


The 'REAL' use of copper head gaskets are for the constant removal of the cyl.head i.e racing where it's a norm to pull the head and check the piston tops burn pattern and ring area for damage as well as a visual inspection of the valves thus saving money on head gaskets.
Usually the cyl.block and or head has been grooved to accept a O-ring for a better seal. Without the O-ring the cyl.head will move around on the gasket (which is normal) and cause 'in the long run' to start leaking.


Best you stick with a stock gasket or FELPRO


BTW, I've seen severasl 'COPPER' head gaskets fail when they were used for 'normal' operation...and they failed not from the installer but from head movement.

Just my 2-cents

if all surfaces are prepared correctly copper lasts as long as anything .. o-ringing is for 12 to 1 comp..-sg

is 1/8 to thick for a 1.6 8v BUILT sammy engine?

oh and can you make these for a 22R-E?
