390 Manifold Fit

Hi Guys, I just bought a rebuilt 390 Ford FE engine and the last and the front two bolts do not align with the head. This manifold was used on other blocks and there was no problem mounting it so I'm looking for answers. I'm questioning wheather their or other thinner gaskets that it under the front and the back of the manifold to allow it to set down farther on the heads so I could bolt it up or could the heads have been shaved to the extent that the manifold does not go down far enough to align the bolts?? Any and all input into curing this problem will be appreciated. Mel

Manifold needs to be milled if the heads were. Bottom cut should be 70% of the head cut.

Thanks Old Bogie, I guess I will have to find out if the heads were milled but Thanks for your answer.

I'll keep harping on this until they shovel dirt in my face......
GET THE BLOCK SQUARE FIRST, then you can square up everything else. Have your machine shop inspect the main bearing bores for being round and parallel with each other, then register the block on the mains and cut the block decks parallel to the mains.

Do this BASIC operation and make the motor go together like it was intended to by the engineers who drafted it out on a clean sheet of paper.

is the manifold cast iron,if yes us the center bolts to pull it into place,be sure manifold is centered. some older fes had a dowel at front of block and a slot in intake,i think the dowel was to hold cork gasket(be sure the manifold has the slot,or remov dowel if its ther. if manifold is alum posibly warped. good luck.
if manifold cast lower it on with a crane to be sure gaskets ar in place,glew with a good cement to the heads and grease the surface wher manifold mates
