Help! Cooling issue! Novice

Yes, I am aware that there was more than one gasket. I was diligent in my repair, thank you for mentioning it though. I have been known to miss things from time to time.

I got her all pieced back together and took her out last night to see if that did the trick, and most importantly to make sure that there were no other issues caused by the overheating. I ran it for about three hours from Idle to full throttle, with no issues. the Temp gauge would creep up to 180 and immediately drop back down to 160 in it's ebb and flow. Which is good, I was able to confirm the thermostat was working well. Water pump sealed off good, no leaks. (I used Fel-Pro KARROPAK Tan Fiber Sheet 1/64" Paper gasket for coolant connections) I did get more water in the bilge than expected, upon further investigation, my starboard side exhaust tube's hose clamp had failed, and I had some water leaking out.

Outside of that, I am back in business. Thanks again for everyone's help. I really appreciate all the wisdom received.
