273 rocker arm adjustment

Wow there was alot in that thread...i have the 340 single hole shafts, and my rockers have alot of galling in them.

Is everyone having good results from that thread?

So i am getting a set of 273 rocker arms and 273 shafts from a guy for a $100.

What do you think is the best route to go? should i check and see how the holes line up? add holes/banana grooves? and what about the rockers, should i drill and plug them?

As far as i know the only push rods that are available are these:

I was planning on filing the top of the rockers so the lock nut sits nice and square/flat on them and using this locking adjusters:

So i guess my plan would be:

get the rockers and shafts from a 273 engine.

Check to make sure the 2 holes per each rocker line up with the two holes in the rocker arms?

Bottom hole should have banana grooves?

Some guys where drilling an additonal hole on the rocker arm and plugging a hole with a set screw?

I like the idea of using the lock nut adjusters and filing the top of the rocker arm smooth.

I already clearanced my rockers for the valve springs. and i think my geometery is ok because the wear pattern that is left on the rocker tip is nice and centered up.

Thanks
