Decluttering the stock 318

So, I'm decluttering my original stock 318 w/ 904 in my 1972 Gold Duster. Was wondering if some of the more knowledgeable techs know what pulley set & belt length that I'll need when I remove the A/C. I have a spare Edelbrock performer intake and Holley 4 barrel carb to reinstall on it, and dress her up a bit ....those are my plans. I'm researching a good header set, which I hear is frustrating to install on the drivers side. I have a 360 w/ 340 J heads that I'll be building as I drive this 43,000 mile car. Would you do a cam on the 318? I have mostly everything for the 360 except a new cam. Anybody got any good information that I could use before I tackle this job?

For headers, go with Doug's or TTI... They are the best fit and won't hang below the k-frame to be bent on daily driving...

Watch the online Autozone discounts to get the doug's at a reasonable price, it will save you about $150 - $200....

The headers may require you to run a mini starter from the later 90's trucks, order a starter for a Dakota or Ram with a 318/360 to get the proper mini starter...
