I certainly will. I have a precision straight edge and a flashlight. If I need to get better than that, I have a nice piece of float glass and a tube of Prussian Blue...but Dog help me if I have to open that tube. My elder brother smeared some under the handle of my toolbox once when I was a kid. My hand was blue for months...

Opening up an engine is usually an exercise in "check everything you can" vs "what else can go wrong?" or "gee, I gotta spend more money than I expected". Everything that can be checked will be. Everything will be cleaned to the best of my ability. Valve seats will be eyeballed too. I used to have an old-fashioned hand-crank valve lapping tool, I wonder what happened to it?

Naturally, you can find them on ebay...
