A mate picked up my bike tonight to drop it off for more work. I have a 2010 softail custom with SE 103 street stage 4 kit (SE259E cams and V&H staggered long shots). Getting 96 heads fully ported, Tman 625 cams and V&H pro pipe installed. Thenheadeing to Thundertech for dyno. Should be back on the road in 2 weeks. Will let you know how the upgrades go.

I bought the street kit (Stock 110 heads with bigger valve) thinking I had the Pro kit, the Pro kit has the MVA heads. Runnig 10.5-1

They do have the larger valves. I believe lowervelocity is the problem, as these heads are too big for a 103. Keeping the 110 heads for a bigger motor down the track, want to see how well the ported 96' heads go. I have bit the bullet, bike is booked for a dyno in 2 weeks.
