Hello everyone, I've got new issues with my corvette and want to run them by some of y'all. So this all started when my radiator busted. I replaced the radiator, but then the car wouldn't crank at all. Figured out it was the VATS system and took care of that. I added coolant until the "low coolant" light turned off in the car and the car was running fine for a few minutes. I had just a little bit of coolant left so with the car off I added the last bit of the bottle in.
When I turned it on, the "low coolant" light turned back on and then the oil pressure started fluctuating and slowly dropping. My temperature started to rise as well over 260. I checked under the car and found oil under it. Checked and saw some oil leaking from on of the heads right above the headers for the exhaust.
Would this leak cause the engine to start overheating and turn on the "low coolant" light? Also what's a good way to check if it's just the head gaskets or the head itself has blown and that needs to be replaced? Any advice would help trying to get this thing back go its glory days, thanks. Photos below
Also sorry for some of my terminology im very much a DIYer.

Your valve cover gaskets are leaking. Check you intake manifold for leaks there also. Check your oil level because severely low oil will cause low oil pressure. Also check your oil pressure sending unit and see it is too is leaking. The low coolant light, and high coolant temperature is probably caused by and air bubble in the coolant system that either was added when you topped it off, or became dislodged when you topped it off.

That's what I figured it was. I had hanged the oil when I did the radiator too so I knew I wasn't because the oil was already low. And good thinking ill check the intake and the sending unit as soon as I get back in town. And that figures with the coolant, probably just need to dump it out and start over. I'll give updates when I get back and I install new gaskets.
Also, You need to "burp" the LT1 engine after doing coolant work. There are screws you need to open a bit to let the air out or you will have an air lock in the system and it will overheat.
