No, they do make pro's for the P73 rods. I have them in now. ARP said that the heads were offset to the wrong side, yet there are no clearance issues. Meaning the only way they go in is in the "wrong way". I don't have any bearings yet so I can't really do an accurate test. I thought about using some oiled up masking tape as my "test bearings", of course without the main caps installed, just something for the crank and rods to turn on. If they have clearance issues, ARP will replace them no problem, as per Al, one of their employees.

My machinist said he thought something was up but just assumed that ARP doesn't make mistakes. We'll see what happens.
