So I got the manifold back from Willson and test fit on heads. They are 440-1 (345cc). Chambers were worked on, then heads decked to keep CC correct. This was all done by INDY in their 345 cnc package.
With a .015 gasket I can install bolts but they are at the very top of the slot hole (Meaning the intake cant go down much more)
The port line up pretty good from what I can see with a flash light.
Problem is I can slip a .010 feeler gauge between the intake flange and the intake gasket only on one side (the opposite side of whichever side I tightened down first) only at the top! The bottom touches all the way across just beyond the mounting bolts on the lower portion.
Almost looks as if the angle is wrong. Looks like it needs to be wider then 90deg to sit flush with head surface.
INDY 572 MAXX block, INDY heads, INDY 440-3 Intake
Not sure if I need to add a thicker gasket or mill the intake. Milling intake would require elongating the bolt holes. Adding thicker gasket would bring bolt holes to a middle (proper position)
