Intake leaking, heads milled?

You shouldn't have to pry on the manifold at all to get it to line up.

Ask the machine shop what their "resurface" means.

On a big block Chrysler .0123" should be removed from the intake side of the head for every .010" from the combustion chamber side. Stock, the head should be about 1.000" thick where the short head bolts go through the head on the exhaust side.

I would lay the intake on the engine with no gaskets in place and check bolt hole alignment. Using feeler gauges, see what clearance you have on all four corners, top and bottom of the intake. If the intake manifold bolt holes are high, the head intake side or the intake manifold must be milled. We sometimes have to do some angle milling of the intake to get it to line up parallel with the heads.

When I called the machine shop yesterday, the only answer I could get was if they did mill any, it wouldn't have been any more the .006".... That's a big number to me.... He does not have any records from when I had my heads in there seeing as how it was over a year ago.

Now this is what is interesting. I did this method and all the holes seemed to line up the way they should, and the intake SEEMED to be flush with the heads... With gaskets and windage tray in place, they do not. It seems as though the thickness of the gaskets put the intake side higher than the bolt holes on the cylinder head
