    Standard compression is probably fine. You will want to choose pistons to run around 11.5-12.5:1 with those cams. Make sure to get a GOOD header, and tune the crap out of the thing on a dyno. I wouldn't waste your money on the fuel rail. The stock one is just fine for your build. Spend that money on bigger fuel injectors.

    There are good 4-2-1 headers and there are bad. You want to make sure you have a long tube design with a 2.5" collector. Any smaller and you restrict what these cams can do. I would go with 400cc+ injectors. You can change the pistons, get a thinner head gasket, and/or deck the head to increase compression. Google a B Series compression calculator and go to town. Stock internals (bottom end) will handle this no problem.
