Hydrolock???

All thoughts are spot on
I had a hunch the head gasket was going(gone) because I would periodically see a little white smoke on start up.
But there was no oil in the water or water in the oil.
There WAS rust in the water but that was because I misread some posts on here and I ran pure water for some time.

The rockers on both middle cylinders on both sides (driver & passgr) are dark colored (burnt) so that means some overheating.

I'll get the heads looked at and if not too expensive I'll have them refurbed.
If more than $200 I'll get those ebay EQ specials from that place down in Florida
Clearwater Cylinder Head i think it is
