really all i need to know is if the bolt spacing, port size and design on the head, where the exhaust manafold bolts up to the head, is there a difference in...well anything?
i called weapon r and 2k racing to try and find out and they "dont know" as neither seems to be interested in develpment of 4th gen h22 motors.

Already answered in your thread on H-T, but I'll answer again

The H22A1 from a 4G lude, the H22A4 from a 5G lude, and the H22A from a jap lude all have the same size/pattern exhaust opening. That means that any H22 header will bolt up to the engine. However, the downpipes are all different lengths. The 5G base is the shortest, the 5G SH is next, then comes the 4G. If you intend on putting an SH header on a base model, it will work, but you will have to correct downpipe fitment with an adapter or simply use a welding torch.
