09 prostar horrible Mpg

with my cm871 if i was getting 5.5-6.2 ied be in hog heaven rolling in the dough and i run roughly the same speed.

how do you pop a valve but not pop a piston/liner/block?

rebuilding the head instead of new was probably the first mistake if you read most of the posts on here if the head comes off new goes on. rebuilt head means lost tolerances because somehow they had to get the new seats in and so far most remanned heads have failed very early in life.

i dont know where you run but lately in the midwest the wind has been atrocious 20-30mph almost every damn day for the last week or 2.
