Tony D Posted March 13, 2005 Share Posted March 13, 2005 Actually, Mack, the Dart Heads on a SBC are something totally different. They keep same valve spacing and configuration, as well as having similar water inlets and outlets. Basically they are a "reworked stock head". A more valid comparison would the the DOHC or pushrod 4-valve heads that you can buy for a Chevy. They are almost universally disallowed in most racing sanctioning bodies' regulations due to costs. The SCTA will class that head as a definite class changer due to having more cams than stock, so it moves the cars from PRO(duction) to MOD9ified) where the speed to make a record are sometimes 50 and 75mph higher!
