There are 2 TDC positions. One is the exhaust stroke with exhaust valve open. The other is both valves closed at top of compression stroke. This is the TDC you want. With the head cover off, the cams will be down and neutral. Head cover on, you should be able to feel the valve rocker arms are free and have a little movement meaning they are not contacting the valve stems and are not impeding full closure. If not they are adjusted too tight and will cause a valve to be open at TDC.
