If the engine is still sitting on a pallet take a few pics of sides, front and rear. Pay attention to the cam plug location at the rear of the motor. It will tell if you have a solid or juice cam. But either way, comments above regarding break-in should be heeded. Even more so if you are running a solid flat tappet. Seen and heard of several folks that have "wiped" their cam in the first few miles because they didn't use proper break-in
oil or started right away with
synthetic.
All IMHO...
