if you look closer at the pic above you can see the little spacers between the head of the bolt and the intake on the front bolts........see?

 

Yeah i see but did you just eyeball it for the correct angle or did you have a way of measuring?

 

i measured it i made a jig for the original intake in the bridgeport and found the angle with the head.......then i put the new intake on the jig and moved the head till the mill fit in the hole correctly.......the angle difference told me the angle i had to make the spacers for
