Worth the trouble?

If he goes with kb107s he would get more compression, but they weigh alot less than the factory pistons. The h116cp will get him into the 9 to 1 range but the pistons weigh the same as stock dished pistons (according to my scale). This way being on a budget he doesnt have to have it ballanced, it would be a good idea, but i would think he could get away without it. He is running open chamber heads, 0 decking isnt super important, he could always mill the heads to up the compression or run thin head gaskets.
