Been through this and I contacted Paul Kane who knows Jim Miller very well. After a long discussion I purchased the Miller rockers. I tried Crower Back set 1.6 and 1.65, Comp Cams, Scorpion, and the Miller rockers gave me perfect 90 angles on both sides of the rocker. Everyone keeps looking at the valve side for mid lift but tru mid lift has to be looked at from both sides of the rocker arm. No rocker arm can achieve this, and the ones I named cant for sure. I just had a long post on yellow bullet in the valvetrain section. I got a couple suggestions but no one really wanted to get into it. I use to think that a narrow witness mark was the go to answer, but it's only part of it and really the result. I was able to achieve rocker arm roller tip location, pattern and good rushrod angle, and finally after a few years of battling this compromise as everyone calls it, I figured it out. So now I have my Morel Ultra-Pro lifters, Manton 8.00" series 4 push rods Miller rocker arms and some valve springs with 170lbs. on the seat and 450lbs on the nose and yes with Mike Jones hydraulic roller cam. Can't wait for the Hot Rod season !!!
