Valve cover gasket opinion...Cork vs Rubber
Quoting the post made before this one #18 above: "Torque them to 8-12 ft.lbs. Most v.c.gasket leaks come from overtightening."
Please be careful, 1972 Chrysler Factory Service Manual (page 9-93) lists small block torque specs for "cylinder head covers" (valve covers) as 40 INCH/LBS which works out to only 3.33 ft/lbs (40 divided by 12 = 3.33). That's why I only use a screwdriver handle adapted to use a small socket.
