Default HP .49

The .49 has substantially more power than it did originally, Mr. RJL tightened up the tolerances, raised the compression and I think opened up the intake port a little. Turbo was right about the rotary valve, you can get it with a bronze bushing or bearing, don't know if it is ball or tapered roller.
