Another Indy intake and head question

pittsburghracer said

I bought this intake used so who knows what the first owner did. Another project that needs attention one of these days. I have another one that I ran on my 422 for 5 years so I’ll do some mic’ing one of these days. Hugh’s sent me a “wax kit” to check fit like they show in their tech section.

John, I've used shims (like you'd use aligning pump/motor shafts) and feeler gauges to check angles. It won't tell you what angles you're dealing with, but it will tell you if there are different angles. Precision ground washers (ARP head/stud washers) will do the same thing.

With the heads installed, I'll install the intake with shims under the four center bolts. Then stack feeler gauges to measure the gap at the top and the bottom. It's a crude method, but if there is much difference in the angles it'll show.
