You need to find the casting numbers.
Here’s a link of where to look.

Hard to see back there behind the head but todays cameras let you take an easy pic.

Sweet! I have a bora-scope maybe I can use that. 👍

You guys have all been more helpful than you know! Now I just need to find time around life to bust a knuckle and get at it. Thank you all.

I like step 4 1/2, good idea to make sure you have the right balancer.

That book will be very helpful.

Your description of the chain slack sounds like you will need to replace it.

I'd pull the pan, the gaskets don't always like to seal back up after they've been disturbed. But, you could always give it a try without fully removing it. Maybe it'll reseal. If it doesn't you can pull it later and it won't disturb the front cover.
