I believe in the old days the 1g small end was also to fat to fit in the 2g piston but I'm sure that's addressed now that they make a 1g rod with the 2g 22mm end on it. I think the only other thing was to verify no contact on the piston oil squirters. If there is contact Either bend them or go to the evo squirters
