Any info would be greatly appreciated.
    Here's what you need to convey to us:
    Piston deck height.
    Compressed gasket thickness.
    Chamber volume.
    Piston part number or description of the crown configuration.

    If you don't know how to determine these things, ask. There is a multitude of engine builders on this board who will be happy to explain how to obtain the info.

    the bottom end was built when I bought it so I don't know the technical details. Again, any info would be greatly appreciated

    Have you bolted the heads to the short block yet?

    no, not yet. I'm not sure if I want to run the 1.94s or not yet. I've been told that I may not get the power I'm looking for with them. I may need to go up to a 2.02.

    What kind of power number are you looking for?

    By the way, If the heads aren't on the motor yet, then you have a golden opportunity to measure the piston deck height.

    also, here is a pic of the intake on the block-its not too clear but it gives you somewhat of an idea what I'm working with.

    also, the rockers are 1.6 ratio. The nuts are too small for the studs.

    They are for 3/8" studs. You have 7/16" studs in the heads. Or at least that would be my best guess.
