hardened valve seats L78

I remember a thread a couple of years ago either here or Team Camaro discussing the hazard of using Av gas. Something about it being refined to burn at higher altitudes and that it was not good for street use. There were some detailed analysis included. I buy Trick Racing fuel and put five gallons in and fill up with 92 Octane. I then fill up once more with 8-10 gallons before adding another 5 gal of Trick. I run this way in the L79 and the Deuce and they run great. In the Camaro I run straight Trick since it does not get driven much. I have heard bad stories about what octane booster does to paint if you should spill!! I usually go through a drum a summer using this technique. Jim
