How do you measure valve guide bore?
My exhaust valves feel a bit too wobbly, so I'm trying to determine of the valve-to-guide clearance is out of spec. The valves check out fine, but I'm not sure how to measure the guide bores. Some sort of tiny dial bore gauge or something?

Hmmm... What are these things called? I wonder if I can buy just the one size I need.

Hole (bore) gauges on ebay:

I think pomansouth01 is referring to a tapered pilot, which is a good way to measure the minimum size of the bore. You'll want to measure the maximum size, though, to indicate wear. You'll need a good micrometer to go with the bore gauge.

Re: (Mikey3000)
You can also use a split ball gauge (small hole/small bore gauge), which will be much more accurate, and is expandable so that you get a good fit, like a mic or feeler gauge.
A small set (usually 4 or 5 different ones) can run you about 80 bucks, but I would not use this if its a one time only deal, since you really should use a micrometer with this as well.
