Have a tube of Permatex, non drying Prussian Blue, that I have not used in years. Might try putting that on the edge of each valve head. Doing an initial torque down, crank engine by hand, pull head and see if there is any blue on chamber?
Or not a workable idea? Valves my open a bit further at running rpm?
