I dont know where you are located. But we have the same vacuum rule here in south TN/North AL. Call a man named Ed Nix @ Nix Machine & Balance. He is a master at these cams and has some in stock. (931) 762-3977.
Also on the engines we have build for vacume rules we run the dist. locked as you will create more vacume at max. advance. And we tend to stay with a single pattern cam as well.
Keep the duration @.050 down below 235 and a 112 LC and you should be fine.
With good rings/V-max lifters/good carb spacer etc. you might be able to run a little more but this should be safe.
what would be a good carb spacer?
HVH and Flow Design 1" both work well with the HVH being a little better all around I believe
