Small port heads, big port intake. How bad?

raised?
last one i looked at width wise hung into the oval port window...but hey if you have'em ..I won't question what you say.

btw it costs money to cast a new small port window'd 4 barrel intake so thats how it ended up being used that way.

what came 1st?
the big port intake on the small port head?
or the matched big port intake/big port heads?

This was an old manifold, they quit selling it decades ago. I don't recall which came first, if there even was a first. All I'm trying to say is the port mismatch is the least of his concerns, it really doesn't make that much of a difference especially with a mild build like that.
