I would say like this, IF you want to mount it in a special way use the opend end towards the exhaust.
Only one reson for that is to balance the piston better. Then if it makes a difference?? Feels better atleast.

Thing is that the missmatch of the third transfer port is that it will be a port instead of nothing there. So it should be like that. If it`s good???
The missmatch on the transferport towards the boost is not so good and may need a dremel mod.....
I have a hard time to understand why you want to...
Gary, get yourself a good modern servos and alot of your problem will go away.
FP-148 is a Futaba STD servo that will not work so good as a steering servo.
The S9301 and S9302 can work but still it will not compare with todays technology.
