third make sure your valves are set with pumped up lifters, especially on hyd. lifters, if set non pumped up can be set to tight and when lifters do pump up it will be to much and put you in to coil bind.
my question? are they a Rhodes style lifter, a anti-pump up.
don't know what type lifters, but when they were out for over 2 months, i wanted to pump them up , i put them in some oil and put a pushrod in it and i could not get it to pump,,it would not move up and down,,,but they are not solid lifters,,,,as there is a oil hole in the side
it ran great, 50psi oil,,,oil coming out of the rocker, back of till click, tighten 1/2 turn, did the other side, and heard it snap from one of the first ones i did
