The previous guys have offered lots of good advice here. MP does make a stamped rocker with more material in the push rod area and a good set of anti-pump up lifters is a great idea. If you have to replace everything you might consider going with a solid cam. You can probably find some adjustable rockers here for a fair price. It`s also a good time to add an oil pressure light to your set-up. It`s much easier to spot a light come on than to read an oil pressure gauge, that way you can shut things down quickly before irreparable damage is done.
