Honestly I rarely have my big block head adapter on my bench anymore. And when I did earlier this year to flow my buddy’s Victor head I had my big bore head adapter on. I guess curiosity has never beaten out laziness. Lol. I finally got my Winona valve seat grinder wired up and leveled up this week. A buddy of mine that had used one is hopefully stopping over Tuesday to shorten my learning curve and seeing what I should order from Silver Seal or Goodson. Intakes are supposed to be dropped off by my son today so I’ll get started on those ASAP.
