Identification on used Mopar Crate 360

Iwent to look at the engine and the owner had paperwork saying it was part number P5007646 which was listed as a 395 HP version of the 360. I will probably buy it, but I am concerned about hood clearance with the M1 manifold. It will go in a 1968 GTS Dart. Edelbrock only lists their Air Gap manifold as fitting the Magnum block. It is about the same height as the M1. I will start a new thread with that question unless anyone reading this has experience using the crate motor with the stock hood.

Thanks
