Pressure build up in radiator

[cbarge]

Maybe intake manifold leak?

Big blocks have " dry intakes"
No coolant flows through them, unlike small blocks

Hello everyone, here with another issue I'm hoping to get some insight on.
1965 Chrysler New Yorker, 413 wedge big block.
Everytime I drive it, no more than 5-10 minutes, it gets really hot or should I say really steamy! I haven't been able to drive it more than 10 minutes without having to pull off the road and let it sit an hour to cool down, I've gone through 3 lower radiator hoses in the last month. Crazy pressure building up in the radiator. I've pulled the stat to run without it, I've replaced the radiator with shroud and electric fan, I bypassed the heater core - still doing the same!
I'm thinking head gaskets, piston rings... Can someone point me in the right direction?

My 68 fury 383 was doing that I put anew radiator in and it runs cool now
