TX team,
building up confidence, as I love straight stuff = flat
unless someone can tell me how much to mill from my Edelbrock down I will go my approache ..put engine it with loose header, then measure the OPTIMUM on hight possible..then mill it.
TX again..

3/8", from 0 in the front, to 3/8" in the back, to get the pad level.
I don't know the total to lower it to use a stock air cleaner though although I DO NOT think that particular manifold will have an issue with not enough plenum volume if you cut it down even another 1/2" beyond that?
You need to talk to someone who does race prep for the heads and the intakes with a flow bench.
They will know for sure how much you can cut it down.
There may and for sure are going to be alternative opinions on this but Edelbrock's are not particularly good flowing manifolds out of the box.
In fact, often the stock iron manifolds flow better. The biggest advantage to the Edelbrock's traditionally have been the lower weight of the aluminum.
I would EXPECT that even the RACE application Edelbrocks NEED individual runner porting to deliver what they were advertised to be.
