Are cast cores that have hardened surfaces "good enough" or do we have to go billet and go with a bronze distributor drive? Or have they figured that out. As for the paint, check those lifters if they are hydros, very small trash in check valve will hold them open and cause noise. Seems Comp would keep old "warranty" stock on hand to replace their old design at least until they exhaust the supply chain. Imagine: "We got these super cool rebuildable lifters, last ones youll buy!" and then next year they change the roller diameter and dont keep any old stock to rebuild the thousands they sold. That would be class action lawsuit stuff. Lunati. Maybe Engle because they are very close.
