Wegner Automotive makes steam vent adapter blocks that employ a 1/8 NPT so that you can run the vent line of your choice. I just checked their site, and it's currently being upgraded. On mine, I went from the 1/8 NPT to 1/8" compression tubing in order to keep the lines small. Most LS guys go to AN-3.

I'll take a look thanks! Do you know why they decreased the number of cross over tubes in the design? I've seen a kit that locates them all into a central block. I have a fast intake so not much clearance underneath it. Thanks again!
Early LSx motors used all 4 steam vents, and the later ones only used the fronts. That said, keep in mind that in a traditional engine configuration, the front of the motor is higher than the rear (motor sits at an angle). In a mid engine configuration, the motor will sit level (mine does), so there is no high end in the head venting, thus I used all four steam vent ports for this reason. Most of the guys on the LS! forums only vent the two front ports, but of course those motors at angled slightly to the rear.
