Legal Heads for SS/modified

FireSale · 02-03-2019, 05:04 PM

SS/CS is cast iron in line valve heads only. Aftermarket heads need to be on the NHRA Accepted Product List. GM and Pontiac are listed separately so I don't know if you can run Pontiac heads on a Chevy. The national record holder in CS is a 302 Ford running NASCAR iron short track heads. They aren't listed but have a factory part number.

Aftermarket aluminum heads, inline or canted, are allowed in SS/BS. Watch out for the Hancock and Lane car from D6 if you build this.

EDIT: I had difficulty getting responses from tech out here on the West coast for Super Stock Modified classes too. I didn't go ahead with my build until I found the Canadian car I referenced above on Facebook, CR and in the NHRA record book. It's a weight to HP group with few engine and valve restrictions.
