    Valve stems size.

    .453" is by far the most common. There is also .346" and .618". I have never run across a .346" but I have seen the .618" ones on farm equipment. I have short ones in stock: https://fillmanmachining.com/product/08-368-valve-stem/

    Comet vs Aftermarket

    I had trouble with loose rivets in the aftermarket 20 & 30 drivens when they first came out a decade or so ago. One failed before I even made it completely out of the garage door. None lasted more than a month before failing. I think the rivets were too short and not bucked correctly.

    West bend 580

    No worries. West Bend engine model numbers use even last digits for CCW rotation on the recoil side and odd last digits for CW. West Bend CCW 82006 powered chainsaw on the rear of a CW 82007 powered Rokon:

    Chrysler/West Bend SA 825- What is it?

    Some early Nethercutt motorcycles had SA821 engines. The production MK2 models had 82007 engines. I recently purchased the prototype Nehtercutt MK0 and it has an 82001 serial number 1017. This bike was built before the SA821 engines were used. My vote is SA stands for Special Application.
