Small block TrickFlow heads part 1

Something I want to add is that when I set this head on the dial pins were tight. I cracked a head 40 years ago when I had deck cut on a set of heads and didn’t remove the burr on the dial pin holes. It just takes 20 seconds with a round file to fix it. Remember a few pages back when I said the rocker oiling hole was smaller on the deck because of the burr. Well it’s the same issue. It’s so easy to crack a head if they aren’t seated so make a habit of checking this.
