I would take it apart and look before you assume what is wrong, it may need rings or the vale seats re ground. I have re-built a few old briggs engines and have never had to do anything to the valve guide's

If it is smoking, verify first that the valves are worn. Check the other things first, as in rings, valve seats (as has been suggested), breathers, and the carburetor and ignition system. Make sure you are running the right oil level and the right viscosity.
If your valve guides are worn, to fix them you pull the engine down and ream the guides out for 1/32 more clearance for oversize valves.
The oversize valves run $45 for the intake side and $33 for the exhaust side. .

The easiest way I found to check valve guides is to pull the valve out about an inch and wiggle. Excesive movement means the guides/ valve is worn and needs replaced. Hope this info helps. Good luck!
