I have read over and over that the transfer slot on the primary side of a Holley should be exposed .040 to .060 at idle, but what about the secondary transfer slots? Exposed? If so, how much? Getting the front slots uncovered the correct amount had very gratifying results but in order to do so I had to uncover the rear transfer slots. Thinking perhaps I need to shut them back down and just drill the front plates.
