I am part way through putting an edelbrock intake manifold on my 253 and I have noticed that it doesnt sit down far enough in the valley as my heads/block ahve been decked at some stage

how do I measure how much I need taken off? should I just take both my manifolds to a machine shop and ask them to make my new one like my old one?
cheers
