    The gsr head has a little bit smaller combustion chamber giving you a slight raise in compression. like +.2. I remember from a while back someone showing a graph of air flow for a gsr head vs b16 head and they were pretty close together.

    If your car is OBD0, get the b16, if not, then choose either the GSR or the b16 of your car's OBD.

    I thought I read somewhere that the b16 head was the better flowing head.

    They both have their high points and low points, but a side by side comparison shows that they're both pretty equal as far as flow.

    10.5:1? why bother going aftermarket for that. you can get some JDM GSR pistons and be right there, or some itr pistsons and go to 11.3 ish...

    either way, if you're going all motor, i'd suggest the gsr head.
    if you're going turbo/sc/nitrous, go with the b16.

    it really doesn't matter too much. the gains/losses between the two are neglicable, and once you port them, and shroud the chambers out, they are equally capable of hitting big figured.

    gsr makes more mid range, b16 makes more top end.

    overall area of graph is about the same cfm over the course of a power band.
