New 408 build finally started

Honestly I’ve never read that thread. I started to and from what I saw was stuff most of us that have been around have been doing for years. (I should take a morning and read it) It will be tubed for sure. I did drag out my old and newer engine books today mainly because I forgot about posting up some head porting books I’ve accumulated.
When you drill the block to tube it, do you use a mill? Or just do it by hand?
