yes. they should be available. your head may be salvagable too. a skilled machinist should be able to straighten it, i think, and plane it again. so that the bottom is parallel with the top. this will work as long as the thinnest part is thicker than the minimum thickness. it is possible too that the cam towers can be made to work too, but this i am not sure of.

my machinist and i had this discussion before but i cannot remember about the towers.

good luck.
