Anyone install Edlebrock aluminum heads ?

Please get it out of your mind about milling the intake. That is one of the stupidest thing that guys do. Your machine shop should know the formula and the proper way of doing this is cut what you want off the head deck surface them calculate what is needed to remove off the intake face of the HEAD. That way you don’t have mismatched heads and intakes and can change your combo at ease. Many times you don’t even have to worry about the intake face but alignment needs checked. Edelbrock Head quality control sucks now so I would have them checked out too as mentioned above.

The issue is it doesn't matter which you mill...the face of the head or the intake. Once you are done, those parts only for with those parts. Just like a complete balance job.

And I know that I've milled many intakes right out of the box on blocks and heads that didn't have any milling (or very little milling) because the ports didn't line up. Just because the bolts go in doesn't matter. The port must line up and the bolt hole are what they are.

Just did a Pontiac this spring. Bought a NOS intake that was in the original box, unmolested. The engine had never been apart. And I had to take .060 off both sides.

Tolerance stack up will bit you if you're not careful.
