i am rebuilding a 1934 207ci six for occasional use...parades etc...the short block turns freely and has little cylinder ware...the head on the other hand had two stuck valves with bent push rods...after liberally dousing the valves with penetrants they came loose and move freely...there seems to be little slop...just stuck valves...the valves were stuck for probably fifty years...this is the question...??...since the engine is in good shape is it feasible to reassemble the engine and run it to determine the extent of valve damage....?
