I'm not sure if the VAC design maybe has the same issues.
Updated design of exactly what?

So did Supertech conclude the valves were the problem, how did they adress this problem?

Itís a new valve, retainer, and shim design apparently.

Interesting, wonder if the new design has enhanced rpm capability and has anyone tested it...not much info in that instagram blurb.

I asked in the comments and didn't get a response. Yeah sucks theres not much detail. A couple people on Michael Essa's page said they're running them as well and it fixed their spitting shims issue but didn't say to what rpm. I figured if I ever pull my head off again I'd give them a call and find out.
