Intake install help- pic

Dont blame the metal gasket for port mismatch, blame Edelbrock and their 30 year old casting molds. Core shift is a maufacturing variable with sand cast molds, take a look at modern casting methods like a crosswind intake (not a sales pitch, but a good example) those ports are very close and repeatable due to their permanent mold process. Gasket matching is SOP on a build as they are all a little off, and it gives you a great pattern to work off of. Hooker header flanges are dreadful, take a look at the end runners, the exhaust port looks like a triangle on some I have seen!
Also any OEM head/block resurfacing affects those steel shim gaskets as they cant fill any void created by head milling. Fiber gaskets are always a better bet on the intakes when you can use them, and the end seals should be suspect to any leaks too as they can vary widely in the space they need to fill. Gasket maker is a sure fire seal on the end seals.
