MP 292H cam too big?
seriuosly though
you said that .015" variations in chamber depth were matched and made flat by hand grinding and polishing?
being a machinist this impresses me - you did this by die grinder? with carbide burr then polishing stone? then measuring at random locations to ensure flatness? this is cool , not being a mechanic but a marine/aviation machinist we fit and hand scape plenty diesel engine parts - I trying to overcome my novice gas mechanic skill i gotta start applying my machinist trade to autpmotive use
you fellas help - ya learn somepin' everyday
