Recommended Posts

heres the stock flow numbers for the 215cc heads and the 230cc heads are not much differant in flow in stock form

.lift...intake.....exhaust

.200....128..........100

.300....182..........136

.400....224..........162

.500....253..........173

.600....256..........176

.700....265..........178

--------------------------------------------------------------------------------

the AFR flow better out of the box but the DART PRO 1s are the prefered head for extensive porting and can be ported to flow bigger numbers by someone that knows how!heres what a professional porting shop says on the DART PRO- 1 heads: http://www.ondoperformance.com/

here is a average sheet on a set of the 230cc versions, they finish up at

238cc's. for a full stage 3 job the price is $975.00, a stage 2 would be

$650.00. intake matching is $75.00

 

this may be a bit better

You're great grumpy! Thanks!! I was comparing them to the fast burn heads on the Sallee Chevy site you listed a while ago. The Dart's do flow well when ported, but the fast burn head sounds pretty good, that is if the production head flows at similar numbers. Pretty good price too!
