VF1000f cam caps

What is the difference between these two camshaft caps. I have 3 motors with various issues and want at least one good one from the 3. Is there a difference between the caps? All I can see is the additional moulding next to the outer mounting bolt.

hi rob,

the top photo is the original cam caps, the second photo with the extra moulding is an updated version,
as far as i understand, honda had concerns when some of the fe’s started to suffer from cam wobble, so strengthened the end of the cam caps hoping to reduce it, the later version also has slightly larger oil holes.

Thanks Pete, I know which way i’ll go now
