I should probably start this by providing a bit of background on my vehicle since I believe it may have ultimately resulted in my currently situation. I bought my Mustang at 32k Miles and have since put another 70k miles on it.

Early on in my owning the vehicle my radiator fan stopped working and caused me to run the car hot a few times until I got it fixed. I believe this may have resulted in warped heads and a slight valve tapping. I continued to run the vehicle with the slight valve tap...
