Too much crank case pressure?

[Michael Smith]

I am some what sure that I have too much crank case pressure. I got on it today and after the run my dip stick was popped out about an inch. I had noticed in the past that occasionaly the dip stick had moved up a little maybe a 1/4 inch if that. Oil pressure cold is 60psi and around 50psi when warm. When getting on it the pressure will move up to around 62-64psi. Engine has about 600miles on it. New 302 block, I beam rods, new stock crank, new bearings, new melling standard volume oil pump, main girdle, canton 7qt pan, B-cam, Edelbrock performer heads, new lifters, push rods, 1.6 roller rockers, new Explorer intake with PCV, I think the routing of the vacum lines are correct? also have changed the oil 3 times since build last one was about 150miles ago. also started leaking oil either out of rear main or out of back of pan. This car is N/A too. I havent noticed any smoke comming from the exhaust. If I do have too much crank case pressure what are my options to fix this problem. Sorry so long just trying to give you all as much info as possible. thanks all for your time.
