Interesting, I was concerned I might have that issue so I primed the engine with the valley open. I have those lifters in my 440 with .650 lift and didn't have that issue.So those results vary. My oil pressure is pretty stable in the car, only drove around town a handful of times though.

Sucks comp won't rebuild lifters in the future. I hope the lifters are tough, they look nice and I like the oil to the needles. [/quote]

.730 lift is what I have. They also dump a ton of oil out the feed holes to the rollers and that might be OK for some situations but not good in others.
