When I measured it a couple of years ago everything was in spec except for one of the exhaust valves (#1 @ .017) Would need .004 thickness to match other exhaust valves.
Haven't taken it apart yet, so I don't know what it looks like under there.
I believe older style tappets had shims, so that's why I thought of that.
I do have the measuring tools (feeler gauges and micrometer) so that's no problem.
Juggling may fix it, or I'll need 1 bucket (unless things have changed alot).
Just being frugal
