Ok guys this post has come to an end. Because of the slotted holes Bill decided not to go ahead and have me gasket match the TrickFlow intake and port it so I’ll be sending it back to him. I’ll never touch another one so don’t ask please. This joined my list with new sets of bare Edelbrock heads I’ll never port another set for any customers. Being that I usually devote at least part of Sundays towards my projects I may start a new post with flow numbers from a ported Super Victor intake if there is any interest.
