Take the cap off and see if it is bubbling with the engine running. If it keeps bubbling after all the lines have been bleed then it's probably the head gasket. If not then i would start with the thermostat. The take out you radiator and clean it out. Not the inside, but the outside. They get all kinds of gunk in there and doesn't allow the air to pass over the fins.

Don't remove the thermostat. Get a new one, if you need to (and make sure it is the correct, long one for the LT1), but don't run without it.

The LT1 pump has a complex series of passages. The thermostat directs the coolant to where it needs to go and when. It is not like an old SBC.

Not very often. It is usually the opposite and sometimes neither.

You can actually cause cooling problems if you remove the thermostat. The thermostat is made to cause resistance in the cooling system. It slows it down so it stays in a radiator for a little bit and actually gets cooled. If you remove it completely it could cause over heating problems. Not always but it is possible.

Head gasket problems are fairly common on these cars so don't rule that out.

When my head gasket went out I did not have oil in my coolant or vice versa. I just had a water jacket leaking into the number 7 cylinder.
