Mechanical Rocker Arm Ratios...

I'm building a 383/432 for street use as we speak. Need super reliable for road trips and heard good things about Crane iron rockers. Have 1.76 ratio iron rockers on my work truck, Ford 428 with 20k miles on them no issues, and yes I just inspected them. For the Mopar BB bought the 1.6 ratio new at a good price. Rocker ratio on engine mock up is 1.63-1.64. Rocker to valve tip contact needs .06 lash cap when using Ferrea valves, OEM 906 iron heads. Contact sweep pattern is good using 8.0 inch pushrod length.
Pushrod angle to rocker adjuster is very good with pushrod centerline pointing slightly toward rocker arm shaft with valve closed, then centerline points slightly away from rocker adjuster Centerline at valve max open; moderate .530 lift.
