Best to do what? You're asking really vague questions.
 
sorry all this stuff is new to me. trying to make more power? just wondering what is the best head to have on the b20 block to make more power. thank you and sorry.
 
If you really want to put together a decent engine combo, then you need to do more then just slap a head on to a block. I'd look into after-market pistons as well. If you use a completely stock bottom end on an LS or B20-VTEC build then you really shouldn't exceed the block's stock redline.

As for which head is the best? There's debate. Any of them will suffice really (B16, GS-R, Type R, etc.). The Type R head is obviously the best, but will also be the most expensive. If you plan to work the head over anyway (after-market valve train, machine work, etc.) then just buy whatever VTEC head you can get for cheap...
