I'm curious too. Hell, have they even SOLD one single unit??? Does anyone have one??? Anyone dynoed one???

They have sold some heads. Just no one has talked to much.

I too want to know what the deal is with this head...They've had them out for a good minute now and still don't have any dyno charts??? What's up with that?? I'm interested in getting either one of these heads, but I need to see some actual numbers and a review on how good the quality of the head is. (i.e. any problems after certain mileage usage, any problems driveability, etc.)

I wish ZPI would say something.

Right now it isn't realy worth it, maybe when someone comes out with some good n/a cams it would be. Just to take the head off and apart for a p&p just isn't worth it to me not when we are still stuck with a very restrictive intake mainfold that is still gonna choke the motor.

this is crazy just then we were trying to find out about stage 2 head now theres stage 3 head already

my friend bought it and they took another few weeks waiting on the head kit for shims but it cost him alot but he has stock pistons

keep us updated..

our motors dont work on lift.. they work on timing.. cams are some what pointless..a p&p head works better.. i should know i have one.

Stage 2 head or Stage 1 + high compression pistons is what I am looking for my NA tC

Stage 2+ N/A Pistons= A LOT OF FUN!
