Personally think the rule change in CS sucks.
Best runs ever (as far as I know off the top of my head, correct if wrong)
9.26 - Mans - Chevy
9.27 - Perno - Ford
9.28 - Bogner - Mopar
Will there be a list of accepted heads?
Same thing happened in A/ND, one brand (chevy) with a 14 degree head can go to 300 CC and flow more than 400 cfm.
This made Ford and Mopar obsolete in the class, WTF, had great parity and now only Chevy!
If anyone knows a Ford or Mopar head that can compete with this, I am in the Market.
