1990 miata cylinder head
 

my brother is looking a cylinder head, cams, valves, fully assembledor not, from a 1.6L 1990-1993 miata.....he has one already that has all the parts so if anybody knows of anything, please let me know....we are trying to get his miata going and he is anxious to see it run because he has replaced lots on it so far.....after fixing the timing problem, he noticed there was wear on the sleve that the exhaust cam rides on and the oil hole was welded shut with hot cam metal.......if anybody knows anything, let me know
thanks
