IRC…Bleed down for original Rhoads is supposed to be .015”-.020” at the valve. So with 1.65s it should be between .009”-.012” tappet.
The pure stock guys have been getting cheated running the Melling SPC-8 or the other white box replica’s of the RA 4. That cam DR file is quite a bit bigger at the low seat timings. Plus it has some Asymmetry from .050 down. The Crower 60919 and Melling SPC-8 I have had did not have that. The Crane looked like a worthy replacement though.
