If the engine sat and has lifters that seized it would be a good idea to check the valves and make sure none of them are sticking too. Especially on the valve that bent the push rod.
With the compression in the low 9s and a RA4 duplicate a variable duration lifter would be a good idea. But with the 4 speed and 3.42s you could certainly get along fine with regular lifters.
A standard hylift johnson lifter would be my pick in a regular lifter. They are the lifter Rhoads modifies. If you wanted a fairly quiet variable duration lifter the Hylift Johnson R lifter would be comparable to the Crane variable duration lifter. Most everything from Crane seems to be 30 days out for delivery. I don’t understand that, crane is in the same building complex as comp and Lunati lol.
With adjustable valve terrain get a set of VPro or Vmax Rhoads and set the lash tighter for less action and quieter operation(IMHO =best)
In the past the Lunati Micro-trol lifters were a step above the comp hi energy lifters quality wise . At least they were in the past. They had a faster and narrower bleed down rate than the hi energy lifters. The hi tech’s from comp are comps variable duration lifters. Lunati’s micro-trols are comparable to the comp magnums lifters. It is hard to keep up with changes in lifters, things change fast in that industry. We try to stay with the Johnsons based lifters as much as we can, but when forced in a corner for a budget performance lifter choice we use the Lunati micro’s.
