If you call 5 cam companies - you will likely get 5 completely different cams unfortunately.
The World Sportsman II heads, (I have a set of them also), like as much lift as you can provide with all means possible in a streetable cam. This is where a roller would help,( if it's possible for you to utilize a roller), along with a stall & more gear.
I hope you don't have a stock shortblock, do you ?
4.56 is a great all around gear for 35's and a smallblock, my '83 K30 was 4.56/350/33's.
Those heads are similar to Vortecs in some aspects, much better intake flow than exhaust, and need to be cammed the same, except they can use far more lift stock and will still improve flow with lifts past .500"orc .550".
