Ron:

If you want to reverse the FA-56 engine's rotation the part to order is SAI130T34. This is less than $15 from Horizon. I'd suggest changing the tappets at the same time, as they tend to seat on the cam, a new cam with old tappets can have a very short life. I alsoglike to change the valve springs if they have any amount of time on them. Tappets and a set of springs will add $13.75 to the bill.
