What did I do wrong?
86 F150 302. Installing a Jegs 4bbl intake manifold. When I set the manifold down on the gaskets and ran down the bolts I can see the top of a hole in the top center of the head on each side. It is like the manifold or gaskets aren't completely covering the head. I used a punch to make sure the holes lined up. If I had to guess I would say that the gaskets are down too far, but I am not sure. I appreciate any assistance y'all can give.

Yeah I noticed that if I tightened down one bolt too much it would shift, so I tried to be even. One side shows slightly more than the other, but it is slight.

I use studs, made out of long bolts with the heads cut off, to help align the manifold. But even then you have to be careful and take it down evenly.

The studs really help if you are using RTV instead of the cork or rubber seals at the front and back of the manifold where it hits the block. With the RTV you don't want to move the manifold sideways or front/rear once it touches the RTV, so the studs prevent that movement.

As for checking, you also have to watch for coolant leaks as the W has coolant passages on the ends of the manifold and they can leak if mis-aligned.

Sure. I am always paranoid about leaks. I will probably check it 100 times after I get it running again. On a side note. I plugged the smog tube holes, but do I also need to plug the smaller holes that bolted the smog tube in place?
