Few things to fix, New and ongoing issue Options

[kagemidnight]

I got my car back with a new 5sfe motor swapped in last week. I have a few kinks that I need to figure out though. First thing is, sometimes my car doesn't start or even turn over. I was told that the battery and alternator are both good but I have a bad terminal on the battery. This seems like an easy fix however, I want to make sure that it is actually the terminals and not something else. I can get it to start without popping the hood and making sure the terminal is snug on the battery, I just pop the clutch in and out a few times and it will usually start up.
Second problem is something that I just noticed today. My car was idling for a few minutes while I ran into a parts store, when I got back in I noticed that the temp was almost all the way up at the H. The second I start to drive the temp drops back down to normal. I somehow had a puncture in the top of my radiator cap so I replaced it thinking it had something to do with that, new cap,coolant is fine and it still idles hot. I took the vacuum hose off my intake and put a breather filter where it goes into the engine last night, could this be what is causing it? Please let me know, I would really appreciate it.
thanks.

visual inspection??

when i had my head gasket done, the shop told me that the head was bad and showed me the holes for the water jacket were corroded and chipped.

i do recommend replacing the pump if you've never changed it or dont know the maintenance history of if.
