Has anyone else bought some of the new ARP Head studs. I bought a set from HPF and the nuts ( the bottom washer part of the nut) would not clear the side of each valve lob. I bought another set from a local speed shop and the nut was 3 mm smaller and everything cleared fine. The piece I am talking about is the nut itself, not the separate washer. ARP supposedly says the kit is correct. I measured everything and it was wrong. Has anyone else had any problems. I should have taken photos.
