Posted By Small-block on 04/01/2008 5:40 AM The 220 Race Series are on the list as an approved head, I didn't see the Platinum Head? 
Dart 23° 220 small-block heads are true racing heads which still allow the use of off-the-shelf pistons, manifolds and headers. they are cast with extra-thick walls and decks to allow extensive porting and modification. A variety of CNC porting options are available. This head should be legal as well, all off the shelf components will bolt on? |
