Bridged Rocker Noise

This is most likely due to "lifter bleed down" when setting overnight. You
should have checked the "dry lash" of the valve train when doing the
original install. Most manufacturers will have a "dry lash" setting for Hyd
lifters. If this lash is too tight you stand a chance of holding the valves
off the seat and burning them. If it's to loose you will have the problem
you are experiencing now. 
 Most OHV motors are pretty forgiving with this setting. They have a pretty
wide tolerance at which they will work OK. OHC motors are MUCH tighter with
this setting. I used to do a LOT of Mitsubishi 2.6 motors. They use lash
adjusters. The dry lash setting on these motors must be between .015 and
.030. If the lash is much more than .035 you will have lifter noise on a
cold start.
 I would try (as other listers have suggested) taking a SMALL amount at a
time off the pedestals until the noise goes away. The only REAL cure for
this is to check the "dry lash" which is tough to do now that the lifters
are full of oil.
