318 LA build

Thanks for the great response wild&crazy guy and rapom65!! When I'm shopping around for Eddy intake, do they make specific LA 318 size for the smaller port heads? Or do I shave the ports on the heads to compensate? I've heard of TTI headers but man they sound super expensive.. Think I'm gonna look into Harold's. My main concern is fit and obviously keeping that price range doable.. I have way too much left on the Swinger to finish..
