I agree, run what makes you smile :finga:
I like the Cowl and I am putting one on my car, do not care if chevy's use them it looks nice. don't want to be in the 70's.#-o
It depends on the class you are running, in general Snell 2000 is good tell 1/1/2012 that is the minium one could run a Snell 2005 is good tell 1/1/2017. Hope that helps.
