These are Crane Gold rockers and I bought the PRW adjusters to pick up some lift, as I was losing over .020 with the Crane ball adjusters. Because the oil hole points so low you have to run 3-4 threads showing on an already tall adjuster, so the kick-out is pretty extreme. It looks like if I just relieve a small portion where the flat meets the round I could pick up .030-.040 and adjuster would sit flat on rocker and possibly distribute the load a little better. I do not have pushrods yet but while shopping I did noticed there is better pricing, more availability and more options (i.e. tapered) to certain sizes, so having a little more room to adjust and getting the pushrod as long and strong as possible is a goal. You can find some pretty nice NASCAR leftovers on the cheap. I am running a mild flat tappet so I am only 150/350 on spring pressure so I don’t feel like I am pushing anything stress wise well I do spin it 7,000.
