Did you check coil bind clearance while you had the heads off/apart?
I did when the springs broke. I will go thru the exercise again.

If some bleed off and others don't, how do you know if your setting preload correctly? If they are still pumped up, some are collapsed, some are stuck, how do you know if it is being done right and all are uniform?

Is the lifter is supposed to be in the middle of its travel when set cold? Is it supposed to be bled off, pumped up, etc? Seems like you would need to set it while running to get them all uniform. If set while running do you increase the preload twist to compensate for the lifters being pumped up with oil pressure?
