??? P72-1 vs. P72-2 ??? -- B18C Head-->What's the Difference?? Help!!

I've noticed that some GSr/Sir-g heads say P72-1 and some say P72-2. What exactly does the -1 or -2 stand for. One is newer than the other no? but which one is newer?

Any answers would be appreciated thanks!

This is correct. The numbers can range from -0 up to -4.

I've personally only seen -1 and -2. -2 come on the JDM cars and the later US cars (98+?). -1 came on the 94-95 USs. I have compared them multiple times and there is zero difference.....none, at all.
