Boost pressure isn't the problem. Boost pressure is a measure of restriction in the system. Your cylinder pressure is going to be the thing to watch. @ 1200hp your going to need to make sure everything is perfect with an MLS and even then your probably going to push some water. There are other head gasket options that offer more reliability at that power level with 4 bolt heads and aftermarket castings. I think Brian made closer to 1700hp before he started pushing water.
