Sprocket bolts seems grinding in drive slots, wrong timing set oem roller ?
Oil pump drive dident looks so good,cracked tighten more than 13ft-lbs or can it be any other reasons ?

I made the mistake of testing a different brand of cam one time when mine was still a street car. Still had an Opti. The shoulder on the front was too long. Way too much end play. Had the bolts hit like that, and drove the rotor forward into the cap. Tore stuff up. Nothing but Comp Cams in my engines now.
