Looking good what kind of allen frost plugs are those???? Or am I missing something , you did in this build to install them?
That is something Chris did. He does it with most of his motors and has his own process and tooling to do it. I 'm sure it's a lot of work. It's a straight thread o-ring plug like you would get in a TA aluminum block ot most aftermarket aluminum blocks. No worries of popping a plug out and getting water under the tires.
