318 DQ's

Hey everyone so I have some really dumb questions about my 318.... It's the matching number for my 72 Duster...

I have completely gutted the motor and am waiting to take it to the machine shop, she has never been rebuilt before. The machine shop was going to deck it for me and do all the machine work. I will be adding a set of Eddy heads, air gap and running the Mopar .509 cam.

1. Is it worth it to deck the block? (I have read the 273 decking forum and still have mixed feelings)
2. I am thinking of throwing in a forged crank. I want this motor to last a while and pass it down to the kiddo someday. Is the forged crank really any better?

The list continued in my head but I totally forgot! Thanks again for all your help and advice in advance!!!
