Larry, the first thing I would check is clearances between the valve guides
and valves. If the DPO had the valve guides replaced and did not get the
proper clearance then there is a possibility that the valves will hang up
when things get warm and expand (uh, don't ask me how I know this please).
Since you are going to have to replace some rockers anyhow why not toss in
some new Roller Rockers. There are a couple of gentlemen on this list that
is making some pretty nice sets.
Good Luck
