joshua,
    right now you are going just on the piston 'expected' numbers. i would take
an actual compression check to verify before going much further.

compression can't be THAT crazy. The pistons are supposed to be for a 10.8:1 2L
block (they're JE). The head isn't decked or anything (it's still got 180K miles
on it).

prefer not to make this a requirement for my daily driver.
