This is the post by the owner of the new motorthat got me


“So it turns out that blueprint engines run hotter during break-in. I got ahold of a service guy there, and he said 210-220 is what the typically what they run during break in, and after about 500-1000 miles should slowly come down to 180 degrees. I do see the posts talking about that my timing is not advanced enough, I could maybe put lighter springs in so the full advance kicks in a lot sooner than 4000, but I can’t make it go past 34 degrees. That’s the max blueprint recommends.”
