1. Reluctant yes. I was not aware that ram air was allowed until Nationals. If "ram air" is legal then using the fog light seems right.
2. A strong NO. We have a compression limit and should only have one criteria for "legal". Using thickness as a "guide" during tech is fine to determine if more scrutiny is warranted but having another, separate rule to DQ someone is wrong and unnecessary and NASA has plenty of rules now to deal with the compression issue. If it ain't broke, don't fix it, NO NEW RULES.
In addition to the above, it should be pointed out that there is no "proof" offered up that the proposed limits equate to a head that is over compression. The head is only part of the volume of the compression chamber. The height of the pistons in the block (is that deck height?), the depth of the valves in the head and the thickness of the gasket all contribute to the compression chamber volume. There was discussion about Charlie's head thickness vs the proposed standard. His head was legal with the standard gasket and would be legal even if thinner than the proposed standard with a thicker, legal Porsche gasket. How does it make any sense to DQ someone if their compression is at or below 10.5 just because of the head measurement?
Use the head thickness as a "guide" for more checking but do not make it another "rule". Making rules up without proper "proof" that they are, in fact, correct makes for bad rule making and this one is bad.
If it ain't broke, don't fix it. NO NEW RULES.
