273 adjustable rockers need refurbish.

I can't post pictures here or I would.

I had at least threelifters that had less than zero pre load. I checked across the tops of the valves with a straight edge and they were not even, I took them back for them to correct this problem.

.010 shaved off the heads at that time. I ported the heads myself, most of the work was on the exhaust side,some bowl work. Going into Doug's headers.

.040 over kb167 piston, block machined,pistons are between .004 and .006 down in t the hole. 028 head gasket. Heads cc'd out at 65cc

I was told that equals 9.46 compression.
