They recommended their 977-16s. 150 on the seat pressure and 441 on the spring rate.

I believe my AFR's have the big block beehives setup @ 150 on the seat (set up by LE).

I believe you are talking about the 26120 beehives, these require longer valves to have the right spring pressures/installed height. Thats the information I got when setting up my valvetrain.

65 cc chambers

214 cc intake port
