    1999 Yamaha XLL FPP triples

    i have a 99 xll with triples, riva rec girdled heads, updated powervalves, triple water box, flame arrestors, jetted, advent igniton, 14/21 solas, aftermarket reeds, stuffers, trued and welded crank. I want to big bore this setup, i am looking for tried and true advice on my project. I am looking for which bb kit to use, who to have done what needs to be done, all the assembly and final tuning i can handle. I have heard of a 1390 kit but groupk tells me i would have to run 100+ octane to make it work with triples, can the heads be modified to run less octane, very hard to find here and very expensive, but will do it if no other way. I want to make her as fast as i can feasibly do within reason. I already have many hours into this boat and i am not giving up on her. please someone who knows their stuff get a hold of me and lets talk.
