    what 2.1 and 2.0 are you refering to?? did you mean to post this in the Prelude section and not the Integra section???

    if so the B21a1 head out of the 91 lude will fit onto the B20a5 out of the 88-90 lude..... just need to match the headgasket to the head and not the block

    if its not the lude then dis-reguard my comment lol

    yes it is for prelude but what i am woundering is if all the oil and water ports are the same and if they will line up because if thats the case why would the head gasket kit be different

    the head gasket is different because the cooling jets are different sizes.....

    just make sure that you have the right head gasket and you will be just fine...... ive put a B21 head onto a B20 block.... just needed the B21 head gasket and never had issues yet

    Yes you will lose power, since you are going from a 2.0 liter compression to a 2.1 liter compression.
    Your swap of heads will be fine for a turbo application on the lude, but your daily driving N/A power will drop. Lower compression means less power.
