When they let the valve job rule go, not much was mentioned about it. Mention roller rockers and suddenly we are becoming Super Stockers. If people were suggesting allowing any ratio, I would agree, but there is a negligible performance improvement going to rollers of the same ratio. IHRA has already gone this way, as far as I can tell there hasn't been a drastic drop in ETs as a result.
