Why not just get Brzezinski Heads if you are going to do that? One of my dad's favorite stories was right after the Payne's reopened Skyline my dad was running a late model there. The rule was stock intake, but my dad was running a Brzenzinski intake that Bob Gentile loaned him to try. Frankie knew people were running cheated up intakes so he made the top 5 pull theirs. The tech inspector spent extra time on my dad's and ended up showing it to Frank. Frank gathered everyone together and told them all that everyone's should look like my dad's by the next week, because his was the only one that hadn't had work done to it. My dad still laughs about that one. The next season they allowed aftermarket intakes so it wasn't a big deal then.
