Manifold doesn't line up

-
I proceeded with the printoseal gaskets/Right Stuff and no seal. I think it was close, but it didn't look quite right.

I've ordered some .125 thick intake gaskets, hopefully that will work. I have exactly one month until I need to drive this thing onto the transport to go to Austin and there's still a lot to do. No pressure...

2 things you can do...ones a pain in the *** and costs you more money than other.
1. Double gasket the intake or buy the .125 thick kind mentioned.
Or..
2. Pull the heads and mill them .040 each chamber side...so the gap narrows and intake fits with stock gaskets. lol I'm going over board on purpose for the sale of humor..

Buy gaskets 1st.

I would be curious as to the angle the intake surfaces were machined at. One thing you can't really see in the valley side of the gasket surface. @MOPAROFFICIAL , are those supposed to be 90°?

90? From the block deck? Think they are like 135 or something, wider. Honestly in that regard I've never checked. I've always made an even cut , if performance or blueprint..then I will cc chambers and if need be ,take more off one end or just open up a chamber some if that kind of deal.
I have encountered many older/early edelbrock intake manifolds , like ld340's ..to be tapered to one end. Many 90's and up edelbrocks seem to be too big and need cutting. The wieands all seem to be made to fit a basically stock engine, like every deck factory 'over' spec.

I was sitting at the kitchen table angling my hands to guess what the angle was. That's why I asked.

No clearance at the China wall but the angle doesn't change. It almost looks like the OP's heads are machined at 75°. Sticking a 4" feeler gauge into the center of the port doesn't tell us what the valley end of the surface is like. Rebuilt heads could be almost anything. If machined correctly, a thicker gasket will work as long as they were machined correctly. Many aren't.
 
OP needs to verify the intake face angle on the intake and on the engine. It should be 87°. I use a digital protractor to do this. Once verified use an intake gasket of proper thickness to align the attaching holes.

Starrett (USA) Brown and Sharpe (Sweden) and Mitutoyo (Japan and Aurora, Illinois) in that order. Nothing wrong with Mit. precision measuring instruments. I personally like B&S myself.

You made the right move with the thicker gaskets. The way the bolt hole was lining up in the prior pix, with the threaded hole in the head lined up at the top of the hole in the manifold, was not going to work. The manifold moves downward as the bolts are tightened and no way it would be able to do that as it was last shown. Hopefully they are thick enough!

IIRC... Last time I looked, Starrett's least expensive caliper was made in China. Mitutoyo's is made in Brazil so I went with Mitutoyo.
 
Got a question for you...I know that it has been some time since you posted your issue with the 67 Cuda that you have concerning the bolts not lining up when yo change the intake manifold. Now I am having the same issue with my 66 Cuda 273. I am putting the same intake manifold as you the Weiand 8007 and my bolt holes are not lining up. Just wondering did you ever solve this problem and if so can you please share this with me. This car is driving me crazy.

What sized bolts? 64 and 65 had a different bolt size and bolt angle. 66 and newer LA engines were the same.

Grind bolt holes and use angled/wedge shims under bolts.

I solved the problem with .125 thick manifold gaskets: Cometic C5624-125 Cometic Aramid Fiber Intake Gaskets | Summit Racing. I used Right Stuff around the water passages and on the rails, and, as far as I can tell, the intake hasn't leaked a drop.

When I installed the 8007 intake the first time with the original heads, it lined up fine with just regular print-o-seal gaskets. I ran into trouble when I installed remanufactured 302 heads that I didn't realize had been machined. Luckily, the nice folks here helped me figure it out.
 
I appreciate the reply. I am on summit racing now. One of the guys suggested using angled shims wondering if that will actually work. Really willing to try anything at this point. Now that you shared i now realize our problem is slightly different but the info is still priceless.
