cylinder spacers

[redneck_raser]

does any one make cylinder shims thinner than the .250" and .190" to make up for removed material when resurfacing crankcase and the bottom of the cylinder like .020" or .030" thickness or is it not critical???

You can buy different sized bas gaskets,trinity racing and cometic both sell oversized gaskets.There is also a guy on ebay who sells custom thick ones too
