 Many a 907 has burned exhaust valves because checking the valve clearances is a pain in the b. Go ahead and remove the covers, check the clearances, and if the exhaust valves need shimming, install the header with the cam tower off.

It's hard and painful, but not impossible to reach the exhaust manifold nuts. I just like to complain!

The copper nuts with the 12mm head are easier to install and well worth the investment.
