Most all Jesel rockers(shaft rockers) have a cut to clear the pushrod for the problem you have, but I woulddn't try it with the cheaper version Cast() body rocker you have.

A billet aluminum rocker you could cut a clearance relief in.

Definately looks like you need lash caps to make the end of the valve longer.

As has been mentioned, go for the narrowest pattern on the valve tip, don't worry so much about centered, if it is off center but makes the narrowest pattern, that is where it should be.

Go here and read this about correct geometry, and why the method given by many big companies is incorrect http://www.aera.org/ep/downloads/ep1...2010_20-30.pdf
