Thanks for the reply.
My plan is to stay with the stock heads for now, so compression will be about 10.1 or so with the .030 HG. Pipes are FM Jackpot 2-1-2. Currently RCX 4.5 slip-ons, but may switch to CVO cans with Fullsac baffles 2 or 2.25 baffles to help on the low end.
Two up riding primarily and looking for smooth, low end torque improvements more than all out high (5K+) RPM power. I'd like to see the torque a bit left of that which Mr Warlock shows on his dyno run. I must say, his mid and upper results are excellent.
