Well, I'm pretty sure we want to go with the Indy 440 EZ heads as those heads are the best value for the dollar and can be easily upgraded to a higher flowing head with CNC porting down the road. The Stealth and Mopar/Edelbrock heads do not hold that type of potential. I also want heads that will allow me to keep the standard valvetrain. We are a budget bracket racing team, so we try to keep cost as low as possible which is why we ran the 452 Iron Heads for so long. So I was just trying to price whats available.
