We had a set of these heads on a 2000 A4 Corvette with a 224 cam on our Mustang Dyno, the car with these heads made just shy of 400hp at the tires!

There are only 10 of these on our shelves, first come - first served! Normally $2,195...while we have them in stock only $1,995 + shipping (no core charge required!)

Give us a call at the shop to to have a set sent out to you.
