Did you have the block and cylinder head milled before you put the head gasket on? Also what head gasket and torque values are you running with?

I would not use that block seal as it clogs up heater cores and other cooling passage paths. It may be a quick temporary fix but not a long term.

I took the head to a local machine shop ,did do anything with block but cleaned old gasket off..

Was a stock head gasket used or metal? Metal should never be used without block prep as well as the head. What was it torqued to? How much boost are you running? Also, why would you wash the motor with it running?

If the head gasket is leaking it's coming off again. I would not use the gasket maker. It will eventually leak again and cause you more problems.

Stock boost is around 6.8lbs. You should torque head bolts to 72 ft/lbs for a stock application. Do not use any kind of block sealer. Just don't.
I'm having trouble understanding your post but after washing your engine it's missing? Then you took out the spark plugs and found coolant in the cylinder?

Yeah that's what happen ,I don't think it's the head gasket I did a compression test on all cylinders that came back at
120 also pressurized cooling system and its holding not over heating. My quess a ignition coil or wires

From a while back I remember of others having coolant in there also. There is 3 bigger bolts with between each section of the 2 sparkplugs. Clean that area good and see if that is where the leak is starting. Also you have coolant lines that run to the throttle body so it would be a good idea to check those two as well for any leaks.

This not Wright car ran good for 2 months then I notice it started missing above 4 tho rpm so I pull wires off and notice coolant again...

Are the metal caps with the hex head in them leaking in the cylinder head? Other than that you have the small coolant lines that run through the throttle body and ISC valve and the rear heater hose that runs to the heater valve that could be leaking.

Isn't those hex head bolts have oil running threw them not coolant?

The top 4 are for the oil and the bottom 3 (in between 1 and 2, 3 and 4, 5 and 6 sparkplugs) are coolant plugs.

I had a similar problem on my GE motor in my old na i had. Hesitated and stumbled like what you described. You definently have a leak filling your plug gally. A 14mm allen socket will also help you tighten those allen bolts that hold on the gally gasket.
