Rich stated- "...probably will use the Comp Cams 972 springs with a 60211 Crower cam."
Still unconfirmed and a secret. But consider this, on the exhaust lobe at 1.795" installed height in theory it will be .033" away from coil bind with the 972 single coil spring with a true 1.65 rocker ratio using that cam. But again he is using Harland Sharp rocker arms, and assuming an unknown higher ratio.
Not suggesting he is going to do so.... But if he removes his current .050" shim and replaces it with a .030" shim his installed height will now be about 1.825" and thus it will be just a tad above the minimum .060" coil bind distance. But he will now be around 117 lbs on the seat, and after run in they will lose some pressure.
