TECH: 1948 Panhead FL Cylinders
MFM (McFarland Machine I call him) . . . indicated, and utilized a live-center cone and turned these cylinders -.010 off the head gasket, and -.007 off the base to clean 'em up. I had to check the fire-ring flange vs. the cylinder head chamber depth - to verify depth to compress the head gasket fully . . and we do - all ok . . . Now we have equal lengths and flat, true surfaces for our head and base gaskets.
