>> With the new 89mm liners clamped down lightly on top of dry figure 8 
>> gaskets which measure .0145" thick, cylinders 1, 2, and 3 
>> liner?protrusion measures between .003" and .004".? Cylinder #4 
>> protrusion measures between .005" and .006".? My question is.... what are

>>
>> Further, what do you like to use for sealer on the (steel) figure 8's and
