SR SR overheating and running rich?

Problem: After about 20 minutes of driving, my car will start to raise in temperature above the half way mark. If I turn the heater on, I can keep the car under the max temp for quite a while. Also, when ever I stop and start to idle, my car will slowly start to drop in temperature. When it over heats, temps are 200+ . Another thing I noticed is that my oil smelled like Fuel.

Troubleshooting: So I have been troubleshooting this problem for a couple months now. My coolant is good. Topped it off, bled, toppped, bled, checked for leaks under pressure, check for bubbles under throttle, checked for any kind of smoke in the exhaust, everything is showing good for my coolant system. I also pulled the T-Stat out for troubleshooting, and it is still out right now. (T-Stat is good)
I noticed one day while I was checking the dip stick that my oil smelled of fuel. So I checked my fuel pressure and it shows good. I took my injectors out and tested them for leaks, they all show good. I replaced my oil/oil filter. checked for boost leaks to make sure I wasn't loosing metered air other than the BOV upon shifting. Tightened down the BOV a little bit more. Fuel pressure while priming is a little over 40, while running it's about 37.
Spark plugs are clean, but show are just a tiny bit pink. Gapped to 32.
I have two e-fans that pull air towards the motor.

FML: So my car still gets a little too hot, and my oil still gets the smell of gas. Which I think is from running rich. I haven't checked my Compression since the beginning of the year, but I replaced the head gasket in January, along with compression testing and stuff was good.

What's Up In The Hood: I have a stock SR20DET Redtop. FMIC w/BOV, spitfire injection, stock injectors, SR MAF, Wiring Specialties Upper Wire Harness, Mishimoto Aluminum Radiator with dual E-Fans.

Summary: Oil smells like fuel, Engine gets hot, FML, Mom's Spaghetti
