So I'm taking out my Blox HSL's cause Im boosted now. I bought my roommates ITR's from his motor. I took them out myself so I know they wernt binding in his motor. I put them in my head, I used royal purple assembly lube. I torq everything, and the exhaust cam is binding but the intake isn't. I took them out and bolted the cam caps up without the cams and the journals don't have a lip to them at all. I put the cams back in an still the same issue. Any ideas why these are binding in my motor but not my roommates?
