Thanks for the replys. Another question: Has anybody here replaced valve seals on trick flow heads? Do I need a special trick flow seal? I e-mailed the company and they said I do need trick flow seals, but I wonder if they're just trying to make more buiseness for themselves. I think I heard somewhere that you can use the stock ford seals, and I have a set sitting around. Back to the t-stat-- if the motor is running a little rich at 180 it wont hurt anything will it? Thanks
