360 timing

yes on the after market distributor , i have the 5 pin control with ballast and what looks to be an accel coil, large square yellow and tan in color. i like the sound and look of the hei spark set up from trailbeast but not sure if i "need" it.
on the vacuum advance the vc3031 from napa has 11R on the arm. as i said in the now missing posts that is as hi as i can find and as far as application it said it fits High Altitude emission 318's, would a 318 vacuum advance work on my 360. i think it would but not sure.
on the aftermarket distributor which would you recommend and what would I have to purchase other than the distributor itself.
