In my opinion this is the best bang for the buck out there for a bagger.
I bought the SE 103” pistons with barrels, 255 cams with gaskets kit. List price $749, Zanotti’s at about $630 shipped. I had the bike in for a warranty oil leak at the bottom of both barrels so it just cost me the labor to change the cams and a retune. The work was done at Latus HD.
When they had the heads off I picked them up. Took the valves out, cleaned all the powder coating paint from the combustion chamber, ports and polished them smooth. Both exhaust valves were not sealing at about a half-inch area. I lapped the valves in to a total seal, reinstalled the valves with new seals. Total time, about 5 hours, cost $14 bucks.
I talked with Mike Stegman before and he said not to put the SE head gaskets in due to increased compression with these cams can cause pinging. So they just used the gaskets that came with the kit.
Riding impressions are; it will just about idle from a stop, pulls hard down low and starts to give up about 4500rpm just as the dyno sheet shows. A perfect fit for my riding style and it really should be this way from the factory. In the Screaming Eagle bikes it pretty much is. Riding at 70mph in 6th gear yesterday, rolled the throttle and it was right to 90 in a heart beat.
If a person can do this build themselves, they can get over 105tq including the tune for about $1000. My last built made 109tq and cost 3 grand more, that’s a bunch of money for 4 lbs of torque.

I didn't experience any hot start problems and the only time it pinged was when I started off in third gear at a stop. :spank: I kept the rpms between 2700-2900 in 6th gear and going above this, it didn't ping. I plan on getting the bike in for a PC III installation in the near future. The tuner informed me that he will be calibrating every 5% of throttle up til 50% or so. Going beyond that might affect the temperature of the engine and also 85% of normal riding requires less than 50% throttle. When I get this done, I'll be able to post some numbers.
