Empi
Because of the manufacturing process used in making these shims, they may not be exactly the dimension as stated. Doghouse and Empi have no control over any discrepancies there may be. These sets are close enough for the vast majority of users, so Doghouse does not accept any returns for them.
This engine builders note: I recommend a .090 thick copper racing head gasket set over these .090 thick steel cylinder base shims. Bring the piston as far up in the cylinder as you can and get your same clearance in the combustion chamber by doing this. This lets the combustion process take place in the combustion chamber NOT in the cylinder. The more combustion that happens in the combustion chamber the more free horsepower you get.
