I have pretty much gathered up all the parts needed to swap Magnum heads onto my 78 360. I have been reading about the use of small block Chevy 1.6 roller rockers on Magnum heads. If rollers would work, wouldnt 1.6 ratio stamped steel rockers work as well? Summit sells 3/8" stud kits for as little as $12, and a set of 1.6 ratio stamped steel rockers for $61. I have always liked the idea of adjustable rockers with a hydraulic cam, especially when a custom length pushrod is to be used. Also, am I correct in assuming a 1.5 ratio arm wont work? This is all going on a 78 360 shortblock with a Comp XE256 cam. Could I use the stamped steel units, or do they have to be rollers?
