[JC455]

Dino,
I used the FlowTech Headers. They are a 4 tube design. They fit great, but I had to make a couple of mods:
1) I made a SLIGHT dimple in the tube next to the starter solenoid. I wanted a little more clearance just in case something should loosen up and move.
2) I filed the 2nd bolt hole on both sides (back side of #1 and #2 cylinders) for more access.
3) I cut the connecting bridge where the dipstick goes through to aid in positioning them. I found that after I had done this, I could have just filed it a little (oops! :O)

Oh yeah, Make sure you have an extra oil filter adapter gasket and a 7/16" wrench that you can modify (or spend $25.00 at Snap On for the correct(??) wrench).
Good luck,
