Roller Rocker geometry questions

1972DusterPaul said

The Crane Gold rocker arms I bought have the roller tips positioned like the original poster's rocker arms.

When I put the Mopar Performance stamped rocker arms (they came on my engine to begin with) on my Edelbrock heads they line up pretty darn good.

Is there a brand (or brands) or rocker arms that provide the best (better than the Cranes) geometry?

Harland Sharp?
Hughes?
Comp Cams?
PRW?

Or is all a crap shoot?

You might try some Hughes rockers, when they first brought them onto the market they said that they had actually made changes so that the geometry was correct, but nothing is perfect. I think you have a better chance of getting it right with the Hughes ones than the Cranes. The Cranes ones have a design problem, that's what this whole post has been about not sunk valves, or valve stems too long or anything else.

HULLO IT'S THE ROCKERS!!!!
