dang guys... i just redid this lol.well i have a brand new 81mm head gasket. but I'm not about to take it apart. for the third time lol.
according to the compression calculator I should be at 11:9 with the 2 layer (top and bottom)
add .3 for the flat valves... and .2 - .3 for the 7 thousandths off the head resurface... should put me anywhere between 12:4 to 12:6 which Morris who will be my tuner said is perfect.
