That’s your lean cruise. Normaly those are in the .070’s range on a 4150. I’d start .078 as a starting point but, you could remove them initial pay for a drive to see how it acts.Where’s the hole going in your angle channel in the pic I posted? That main body doesn’t even appear to be drilled for a 3rd circuit. So I don’t see it in your blocks or main body. 3 circuit blocks normally look way different. Those are ringers for a 2 circ.
