JDM CNC PI heads with only 500 miles (motor broke the bottom end right after dyno run) I have to install a Timesert into one chamber, decks will be surfaced again. $995 for the pair. They were brand new castings with 8 threads when installed on the motor. These are big dawg PI heads, some nice CNC work here. Only flaw is one spark plug thread was messed up, hence the Timesert.
