"has only seen a few minutes on the engine stand running just to check on leaks an other issues"
If this motor has a new flat tappet cam, you need to break the motor in properly, 20 minutes at varying rpms above 2500 rpm, no idle time! Hopefully, you won't be posting about yet another flat tappet cam failure that will be blamed on everything from cheap off-shore lifters, soft cam cores, or lack of zinc in oil. Aside from my soap box preaching, that is a nice looking motor.
