The problem with the tin tappet chest covers is that they distort easily if overtightened. Many have been distorted at some time in their past even if you've been careful to treat them properly now. I've given up with them all together and now make my own covers from a length of 3" wide, 1/8" thick aluminium plate. Fitted with a rubberised cork sheet gasket behind them, you can tighten them down with no risk of distortion and no leaks.
