was you fellas able to save your valve cover gaskets?. and if so, how?, i cant seem to manage that task, they get expensive after awhile. I wait till the engine is cool., the remove the gaskets and clean them off right away, inspect, and whatnot., then i get my buisness done and install the valve covers. about a weak later they are leaking. I do torque them down to spec. ( i cant remember off top of my head, but aint a whole lot.) Thanks
