These are new, and never installed on any motor. Last I checked Summit racing, and Jegs is selling them for $1449. I upgraded to the competition ports. I also have access to other part #'s with unbeatable prices.


$1249 plus shipping.


On average this is what they flow:
.200 lift(intake/exhaust) AFR-143/113
.300 lift(intake/exhaust) AFR-199/161
.400 lift(intake/exhaust) AFR-246/195
.500 lift(intake/exhaust) AFR-276/214
.600 lift(intake/exhaust) AFR-286/218


You can PM or e-mail me if interested. Take care!
