Who ported & polished your stock TC88 heads? They have the same potential as ported CVO heads. The CVO heads are the same basic casting. You need to have automatic compression releases installed in which ever set of heads you use. Port match the intake to the heads, use 1.90 intake and 1.56 exhaust valves. Springs and retainers & locks to match your cams. 10 - 10.5/1 CR. Ditch the SE cams and go with Andrews 37G gear drive cams. Jims lifters and SE adj. push-rods. SE Billet rocker support and roller rockers. A Fueling oil pump and cam support and Barnett Scorpion clutch. Use the competition baffle in your pipe. Jet carb to match engine.
With bike tuned correctly this combo will give you 120+ft/tq . and 115+hp from 103ci.
1 thing I foregot you have a B engine so you'll need to have the Ballancers and the Crank Balanced togeather, if not she'll shake her self to death.
appreciate the info, head were initially done at local shop. actually im gonna use wood cams tw6h 240 duration 590 lift BIG torque cam dont think torque is gonna be a prob just hoping to get HP number close even though i know been told million time torque is what wins the race
If HP is what your after that cam will give it to you as long as your willing to keep her cranked up, and your heads are set up for it. Remember "B" 6500rpm red-line.
With 103ci B motor and a .590 lift cam and flat top pistons you'll have to have valve clearances cut in the pistons. If you don't trust your ported heads, send the SE heads to Branch Flowmetrics
and let them work their magic on them, along with a set of JE pistons to match.
I'm running their heads & JE piston combo on a 06 103ci Dyna that makes 146HP on pump gas and gets 40mpg on the highway!
The cam I'm running is a Custom grind done for me by Andrews with a .650 lift 314 ID and 312 ED.
I started with a 60mm intake but ended up building my own from billet with a 64mm TB and flow matched Bosh injectors.
