Overheating Issue
Quick History on the Car first
Built Motor. GSR Block .020 Overbore w/ CTR Pistons B16 Head, I assume when it was at the shop they shaved the head a little, BC3 Cams, Eibach Valve Springs, Skunk2 Retainers, Omni Power Valves. Tuned w/ Hondata S200. After about 3 Months my Valve Guides melted or something and a few Valves were damaged. Sent the Head out again and had the Valves replaced with Supertech ones and installed Portflow Valve Guides. Again, I assume the Head was shaved or machined in some way. When I installed the head I had a timing issue and again, damaged a few of the NEW Supertech Valves. I had some Omni Power Valves that were damaged during the first mishap so I used those to replace the less then 5 damaged Supertech Valves. Once again, I'm assuming some machine work was done to the head.
So all in all, my Head has had a good amount of repairs done to it, and is running 3 or 4 Omni Valves and the rest Supertech. And possibly been shaved each time there was work done . . maybe . . . . .
So, everythings good now, motor wise. What was happening was the Car started to heat up a lot faster. I just figured it was because I was still running a fairly stock cooling system. So I upgraded to a new GSR Full Length Radiator, Samco Hoses, new Thermostat, and 2 thin torcflo fans. I noticed a little difference for a little while but again the Car started to overheat. So I figured that maybe the fans weren't kicking on soon enough. So I unpluged the Sensor and jumped it so when the Car was turned on, the Fans would instantly kick on. That didn't help.
So whats happening is after about 20 minutes of driving my STOCK Gauge will start to read just a little bit above the halfway mark and then my AutoMeter Gauge (which is hooked up to the Upper Radiator Hose via a Greddy Radiator Hose Adapter) will start to go up and hit 250. I crank the heat on and both Gauges drop, stock gauge to right below halfway and autometer to about 180-190. I thought maybe since I jumped the sensor that maybe the radiator was so cold that the thermostat would never open, so i plugged the Sensor back in and went for a ride. After 20 minutes both Gauges went up but the only difference was the stock Gauge went up REALLY high. Like all the way up. I stopped, let it cool down and went home.
I popped the hood and it looks like a little bit of coolant is coming from somewhere between the Block and the Head. I can't pinpoint exactly where its coming from. Is it possible the since there was so much machine work done to my head that it is just not sitting correctly on top of the block? Another thing, the Car sat for a while. Maybe I'm just low on coolant? I was told to flush out all the Coolant and put in some stuff, keep the Radiator Cap open and run the Car a little bit to get rid of any air in the System. Then put in some Water Wetter. Do you think it would help if I just ran Water and Water Wetter? Can I even do that and it be safe? What else can be wrong? I know the first thing I am going to do is flush the system and put in some new coolant. Any other ideas?

it seems like a big issue, i had a problem where i kept blowing part of my head gasket but not all of it so there was no oil and coolant mix but it kept overheating, i went from changing out the cap, thermo, pump and radiator until i just finally decided to get a small resurface and get the head redone, apfter that, it was fine, i just continue to watch it, i think it blew the first time from my rebuild because i didnt decided to change all this at once, usually when u work on a rebuild, its good idea to change out all the essential cooling parts and jump ur fan so u know its always on
