engine difference

I am very new at the honda world. I was wondering what the difference is in a b20b and a b20z. I have seen the other comments about them but i don't understand the compression ratio thing and thats all i see posted about them. Also what is your opion on them and which one would you chose.

"B20B, B20Z: The B20 engine is the newcomer in the game and is highly acclaimed by its supporters. It has several key characteristics that give this engine real potential no matter what route you decide to persue. The B20B came on the 1996-1998 CRV and the B20Z came on 1999-2000 CRV. The B20B made 126 hp but the real jewel was the 133lbs of torque that was easily achieved almost anywhere in the RPM band. It is a small displacement engine that has flat torque line!!! Additionally it was a comparatively low compression engine which means that turbocharging to decent levels is possible without the need to spend hundreds on rods or pistons. The B20Z was more or less the same as the B20B but they changed several head characteristics and the compression was bumped up to increase the horsepower to 146." - taken from http://www.automotiveforums.com/vbulletin/t19176.html
It is amazing the information a SEARCH (repeat it with me...SEARCH) can acheive.

Do you know if it is true that a b20b's intake manifold will not fit in a 1990 civic but a b20z's intake manifold will?
