Questions about BPC4082CTC 408/375hp

Hello....I purchased a Blueprint BPC4082CTC from Summit Racing yesterday to install in the wifes 72 Duster...I was wondering if this engine will arrive with 10 or 5 bolt valve covers?...Some of the file photos I have seen feature a chrome 5 bolt while others show a black finned aluminum 10 bolt style?....WIll it have the GM style large cap HEI distributor that I've seen in some photos while others show a stock style Mopar unit?....I am new to Mopars but not in building and working on cars have been a Chevy guy for over 40 years but switched over a couple of years ago starting with a 440+6 69 Roadrunner.....Last question...The Duster currently has an LA 360 with a 727...It was originally a 318 car....Will I need new engine mounts? and will be converting it over to an A833 4spd with the new engine swap. Which flywheel will I need?.....Thank You
