Procomp rockers???

As the the valve lifts, the retainer/rocker clearance grows...

I ran these to 7200 rpm on with my 340 and 410 stroker with 370 psi open pressure.
I use 1.80 1.43 comp spring and manley 1.43 on the 410.

they only hit when I did not line up the rollers/valve tips, after that fix they never hit again.
