How often do you need to check the valve clearance on a NAA?

1, every 40-50 ys at least :)

2, Any time you have the head off, or valve cover off.. or do any valve trian work.

3, If you think there is a problem.. like valve tick.. or if you think you have clearances too tight and notice a compression loss or are burning exhaust valves.

40-50 years is about right. I had my 641 apart recently and checked the valves. All were spot-on except for #1 and the intake was a couple thousandths loose.

when I worked on my 4000 a while back. all the exhaust were spot on.. couldn't check the intake as all the push rods were bent to heck.. which was why I was checking them.. :)
