Ok I got the cam measured and I cant find any specs of what it should be.The 2 inside lobes measure 25.95mm and the 2 outside lobes are 26.25mm is it at least close to specs..I have heard about thes cams having a problem with wearing out..

Your cam seems to be in good condition, mine is under 26mm in all lobes.
