Ive recently had one of my cylinder heads off to do a lil inspection.2000 Windsor pi heads. I'm now re-installing the head and I just went to my local ford dealer to pick up new head bolts. They tell me this new bolt is the updated version. My concern is that it does not use a washer under the head flange like the bolts i removed. I understand the use Of moly based assembly lube. Has anyone used these recently. Any issues with them?
