The Common Rails have multi layered head gaskets stock so at 1:1 drive pressures or close to it 50-55 PSI is no problem. Now, a stocker at that kind of boost will run drive pressures though the roof and will not be kind to a head gasket.
I'm not sure why you can't get any boost out of that thing. I'm running the same turbo on mine but with the 14 exhaust housing and I can run 45 all day long. HTT claims 1:1 drive pressure at 45 PSI with the HTB2 62 so if you are allowed to get it there with no wastegate then I say go for it. Do you have the adjustable boost elbow on there? I would call and talk with Paul at HTT and explain the problem, he may know something.
