Yeah if you look at your picture in post 50 of this thread you can see that the exhaust valve is whats located at what would be the front of the motor. Look and you'll see that ajoining cylinders have mirror image valve layout (exhaust,intake,intake,exhaust,exhaust,intake,inta ke,exhaust). Turn the motor and watch the exhaust open and then close (exhaust stroke) and then the intake open and close (intake stroke) and then bring motor up on TDC on balancer (compresssion stroke).
