Hydraulic Roller Lifters w/LA Block?

You were going to need adjustable rockers even with a hydraulic roller as the stamped rockers won't take much spring with out punching the pr through them. Also I doubt there will be much if any difference in springs need to put solids on it instead of hydraulics.

Right on....... I'm using Hughes rockers and shafts, with the MRL solids. Absolutely perfect friggin geometry and "scrub pattern". They are a little expensive but nowhere near T&D or Jessel. I've been running them for a long time. The last set I had were the 1.5 ratio. I ran em for 4 years and sold them to a buddy for his drag car. He's running almost 700lbs open pressure and has somewhere north of 200 passes on em. Amazing.
