Okay... I haven't seen the rule, as written, but I don't see the problem then.
Everyone knows what the intake face angle should be on all the popular combinations.
That angle should be what's allowed. That, and the v.c. bolt hole limit.
The spacers shouldn't have anything to do with this.
Someone could change the head angle, then build a custom manifold to match it, if it were allowed.

Also, I believe some of the spacers would have to use countersunk bolts into the head, and then they would be covered up by the manifold pattern. So, no, you couldn't just weld the spacers to the manifold.

*Edit : I just read post # 12. I assume this was lifted from the new rule book.. Is this under intakes or heads?
This , too me , looks like NO adapters at all, in S/S.
I guess the saving grace here is that not too much of y'all's money could be going to their lawyers. What a bunch of contradictory gibberish.
