I just recently bought an 02 MXZX 440. It has the high compression heads and was raced. I do not plan to race it. I have bought some LC Domes and want to put them on. My question is what all needs to be done. I have ordered some new gaskets and o rings for the domes as well as a #3 Basegasket. I plan to run 91 fuel in it if i can but it is very likely that i will run 87 some times. I also plan to run a 320 on the PTO and a 330 on the MAG for jets. And 35 for pilots. Is there anything else i should know??? What is everyone reccomendations when doing this. I heard #3 is the proper BG is this right?? I ride at about 1300 feet and in -10 to -30 C or 7 to -22 F weather. Any help or comments please!
