Gal after my own heart;car parts on the table linen.Some may have a different approach but I usually put gasket shelack on the valve cover then stick the gasket on the cover and let it sit for about 30 minutes before I put it back on.Reason being,if you need to adjust the valves again,when you pull the cover the gasket stays on it and you don't have to worry about breaking it.Just clean the oil off of it and slide it back on.Great job,carry on!
