NHRA 2020 Rule Amendment SS Intakes???

Gents, let take a breath. This is getting heated, and while it certainly should be getting heated, a lot of the 'heat' seems to be over the wrong aspect of this rule, at least in my opinion.
Most folks are focusing on the manifold-end of this rule, and also on the 'spacers'.

Since in SS, pretty much any intake manifold modifications are allowed, there is really no concern over this rule affecting the manifold designs out there. Regarding not allowing 'spacers', fine, so now I'll just tig-weld my 'spacer' to the manifold. Its now just a modified manifold, (allowed), or I'll just create an entire manifold from scratch.

The real issue with this rule impacts the HEADS not the manifold. The intake-face angle to combustion-surface angle limitation is the reason this rule is a very big deal, unprecedented, and in my opinion, is unfair. This was never previously a dimension that was called out on the blueprint specs, or the rulebook. Hence up to this point folks were permitted to do whatever they desired regarding this angle.

As a result of this new rule, I believe a lot more heads are now 'illegal' than the intended batch of heads that the folks who lobbied for this rule intended to target.
