    I just had three done one at GroupK it was for the 65U motor and one for the 1200R at Pro-Tec Both came back looking good I used Pro-Tec for the turn around time they did in three days $135 it was a beautiful Job he cut it to my spec which was 145 PSI we have lower octane here in Ca. 91 instaed of 93 in most other states. Wayne the Machinist at Pro-Tec is great to work with. He also cut a Pro-Tec head I had that had a ring let go and damage the center cylinder I had it changed from 165 psi to 150 itwas for a 65U also .
