Check compression without a lot of oil in the cylinder---then check it again with several squirts of oil. If it increases on the 2nd test, you have ring seal problem. If it does not, it is in the valve train.
The head gasket should seal right off the bat, without any run in or warm up--unless something has changed with head gasket materials that I don't know about.
A new build eng can have less compression at first, then compression should gets a bit better as rings wear in. Not a lot, but a bit.
The head has 39k miles on it, the bottom end has 28k on it. Both havent been used for a few months. Im using ARP Headstuds and was worried I didnt torque them enough. All aluminum engine/head and I torqued to 65ft/lb.
I would assume I should get over 200psi.
