I kind of got the impression from Corey that 10 pounds of boost would be the limit.

I'll check with Corey on your limit. I would think you could push it past 10.
I used a custom Liner that Ron Woods (RIP) had designed. The liners are 4030 and the have a wider shoulder on the bottom to keep the rocking to a minimum. We had to mill the block where the liner sits to get them to fit as designed. The liners also have more surface area at the head gasket that are secured with Head Studs. We felt we could get 20 psi of boost with that setup. The only problem with my setup is that it's limited to 15 psi of boost because I have the stock valve springs. Well, for now that is...
I bet with the ECM and maybe a little Meth you could go to 15 but that's just me... Corey will have to make that call...
As far as the O-Ring goes. Yes Jerry and I looked at it but went with Ron's setup. We still think it can be done with groves, O-Rings and Jerry's Head Gaskets!
Cheers,
Ron
