Thanks Bernie. I took your suggestion and dug my spare head out of storage. All the intake holes on that head take 22mm of bolt engagement. I drilled the hole noted in my post with a 17/64" drill. Tapped it deeper and now have full thread depth on all 8 intake holes. I had a factory defect. Thanks for your help.
