maybe air in the cooling system how long has it been doing it and when you start the car does it continue to bubble and gurgle or stop after some time has passed
Numerous things could causing bubbling. Trapped air, wrong concentration or lack of antifreeze, bad thermostat,clogged radiator,inoperative cooling fan, bad water pump and last but least a faulty head gasket/head that is leaking compression into cooling system .
I think most of whats in the coolant right now is water. I took the spark plugs out and they dont look wet. I also took the cover off and nothing looks watery or moisturous.
Compression leakage into cooling system due to warped head and or leaking head gasket. Start by draining water out of cooling system ,replace thermostat and adding antifreeze in the correct ammount to raise the boiling point. I remember from previous posts that you already put in a used head and I hope a new head gasket. Was block/head checked for warpage prior to replacing it ? If not that could be part of your problem.
using 1st gen 4A-F/FE bolts uses just a torque for tightening
(IIRC) using 2nd gen 4A-FE bolts uses first a correct torque and then you degree them as they stretch... reusing the 2nd gen bolts isnt gonna work.
I really couldn't tell you if it was 1 or 2 generation bolts. It was the bolts off the new used head. I got to hear the car run that the new used head came off of. I did the sequence right. After I got the car back together, it ran well except for a leak in the back. It sprayed coolant all over the transmission and back of the engine. Not massively, but enough to know sometihng is leaking. This was after a 10 minute drive. The head gauge was fine. So I then proceeded to change the radiator cause it had a crack in it. After changing it i put prolly like 25% antifreeze 75%water. I used what antireeze i had left and just used water deciding if I'm dealing with a leak I'd rather leak water than antifreeze since water is cheaper than antifreeze haha. Now I have some bubbling going on in the coolant resevior. Maybe there is simply too much water in it? I didn't have this problem when I had about 75%antifreze 25%water or closer ratio than that. I haven't dealt with it much, but if there is air in the cooling system, can that cause a car to sputter a little?

ya i personally wouldnt re use head bolts... and a leak could have been a possible warped head?
If you're using pre-mixed antifreeze which i believe is common now at auto part stores, there's no need for water. If you add water, it will boil at a lower hot temperature the more water you add to it. So, if it boils, it can cause air pockets at various points. Or if there's a leak somewhere that's also drawing in air.
Do a leak down test of the cooling system and on the engine cylinders (compression test and leak test).
Hopefully, you know how to check a head or the top mounting surface of a block for warpage. A straight-edge (which is a ruler with no numbers, NOT CHEAP! But dead accurate straight) and a feeler gauge.
