If you haven’t already, email Steve for his valve clearance spreadsheet. Take the math out of the job and it’s just turning wrenches. Follow the instructions carefully. Don’t turn the crank when there’s an empty bucket or you could damage the surface of the cam lobe, maybe the bucket lip. It’s a job that has to be done. Best to learn how to do it yourself.

Will be doing that probably this weekend. Need to order the valve cover gasket in case it gets wrecked during removal. Was going to have my buddy do it but he said he's basically too intimidated by bucket over shim valves.

Your buddy is mistaken - these are shim-over-bucket jobs.
Bucket-over-shim are designs I won't touch if I can avoid it. Iow, I wouldn't buy one.
