There usually is a tightening sequence for the head bolts. Sometimes it can be in several steps. You need a torque wrench. Maybe look into it. There may be consequences if this is not done but I am not an expert only trying to help. So good to see the boys learning these skills. I wish I had been able to do this as a boy. Instead I had to sit in a classroom and learn stupid stuff that was no use to me at all.
Super proud of your workmanship. No one can appreciate work unless they know. .Thank you! It's great to see the boys learning these skills. I wish I could have done this when I was a boy. 🎉🎉
