Last week was a VERY long week. Seemed aside from the good flow numbers everything else was not wanting to co-operate. The HS 1.65 roller rockers actually measured 1.71 which resulted in more lift than expected.

The stock spring retainers were smashing the new posi seals at full lift and the 9.139 stock length pushrods were too short. I borrowed an adjustible pushrod and determined the correct length pushrod (9.252) and it was REALLY pinching the posi seal while rolling the motor over by hand. Lift was being lost due to incorrect rocker geometry. I ordered new 10 degree retainers, 9.252 pushrods, and locks mid week and they finally showed up Friday.

Ran by the machine shop Friday and did a preliminary check. The difference measured from the bottom of the retainer to the top of the seal changed from .520 to .680 just by changing the retainers and locks. The shop is supposed to be resetting the spring heights today with the new retainers and locks. The springs can handle .700 lift, but the retainer to posi seal will ONLY allow for .680....so I will be safe with the .633 lift I'll be running with a little room to upgrade in the future should the need arise. Looks like assembly will resume tomorrow night....
