You just need to take the intake off and have it cut. IF the guy knows how much he cut off the heads, that woud be great. How far off are the bolt holes? A quick test is to remove the intake, take the intake gaskets off, then re-fit the manifold and see if it lines up then. If so, both sides of the manifold need to be cut the thickness of the gaskets. A .020-.030 intake surface cut runs from $65-95 ish dollars depending on your area of the country.

BB I'm assuming. Put a swath of dykem horizontle across the head intake ports end to end on the top and bottom sides on each side and across the intake manifold ports the same way & go "up" a bit with the dykem on each of the 4 intake corners (2 on each corner, one for the top and one for the bottom of the ports) so from the top you can see where the lines are at. Set the intake/valley pan/paper gaskets (thick or thin ones you if use them & I would) in place. Measure how much above or below the head horizontle lines the lines on the intake are & give that dimention to the machine shop. iirc you said the heads are already installed so major milling on the intake will make it fit that eng only. Best is to mill the head intake surfaces so the intake can be swapped but no big deal & getting up & running as is is way more important than a potential manifold change in the future. wouldn't hurt to do some slight squaring up of the port openings to get em equal before swabbing the dykem for a more blueprinted intact tract. If you dont want to mess with the dykem you can see how far the head intake bolt holes are below the centerline of the manifold bolt holes & measure as best as you can & give that number to the shop. Backing up: if the intake manifold ports are below the head ports you would need to use thick paper gaskets below & more so on top of the valley pan port openings to move the head port interface higher/inward to match the manifold. Mockup as is & see where you are at

It's a small block.... I haven't tried fitting it yet I'll get to that in the next couple days.....
We'll at least it's seems easier than I had thought! Sometime things just have a way of being way to difficult in this world but this ain't that bad hahaha

make sure you take the little gasket centering pins out of the top of the block.

It's a small block.. Haha. I haven't test fit the intake yet it's still in the box.. I'm gonna try and test fit it this weekend when I get the car home. Blocks been milled a little and the heads have been shaved down. I've only run 1 intake on this motor so I was just getting some input before I started ripping things apart unknowing. Now I see I just need to pull off the old one and text fit it see how the bolt holes look. I'll take a look this weekend and get back to you guys.... Thanks for the help dudes!!!

I have no idea on a small block if intake/head mismatch can lead to a gap that allows oil to be sucked in from lifter chamber, but on my 512 bb stroker, I had a horrid plug fouling issue that took quite some time to troubleshoot and resolve. Resolution was replacing existing heads with a pair of edelbrock aluminum. Evidently my iron heads had once been milled and geometry correction to ensure proper intake geometry had not been done. New heads, all is well.
I remember one old time way to check this was to take intake and with no gasket, set it in position on the heads, but first to run string of dental floss front to rear between head and intake. If it can be pulled out with little or no resistance, further research should be done before installation of intake.
I am talking of a fouled out set of ngk plugs in 50 or less miles. Yes fellows, upon analyses by machine shop, valve guides were all fine.

Check your old bill or talk to your machinist, as he may have cut both the head and intake face. That way you don't end up with everything mismatched.

I'd pull the dowels in the front/rear block rails then dry mockup the intake/your choice of side gaskets with no front/rear gaskets & check the bolt holes height on the face slope & go from there

Not everyone...checking the intake for fit is a key step in any intake swap especially when the block has been decked or the heads have been angle milled. The reason why so many mopars are so slow is because people just toss the cam in dot to dot and slap on an intake for the ultimate oil sucking, powerless engine.
That is usually my first question when riding in an old car...
why is it so slow?
