Lunati VooDoo Question

Question..

Are the lifters noise on Ramp Up ? and not on Idle ?

I sometimes wonder if we here the Valves closing when using header.

I am hoping I just have lifters failings cause this is the 2nd time I have had this noise and last time we just changed a lifter that collapsed.

With this in mind if I only need a lifter I want to purchase 16 new hydraulic ones...

Rusty what is your recommendation on lifters for the Purple Shaft...
