Got water on number 4 cyn could this be head gasket

I do not fully understand your question, but will answer based on a pew probabilities.

If your head gasket is blown, you will get
water or coolant in your oil, oil in your radiator and VERY poor performance.

Water in ONE cylinder is unlikely to be a symptom of a blown head gasket. Are you saying that the other cylinders are fine? What about your spark plugs; any discoloration or moisture?

Must likely, Check the radiator with the cap off ( make sure you removed the cap when the engine is cool) and see if you see bubbles coming up to the cap when the engine is running. Also check for white smoke at the exhaust pipe when the engine is running. This is a sign that water is leaking into the cylinder. Best way to check is use a radiator compression gauge where you pump a low pressure in the radiator and see if it holds the low pressure, if not you do have a leak and the coolant system and the system is not sealed.
