Zimnypit.... if you dont mind me asking.... how much did it set you back after it was all said and done?

I am looking at heads right now... and those numbers look pretty close to the Dart 225 heads. If they perform the same... then it just comes down to price...

Heads like Z's are $1,195.00 per pair assembled.

Good looking heads as well.

Mine are 314.0 and 228.8 at .600"

Gunnar, ever flowed any of these heads to .650"?

I asked the same thing earlier. I dont think he does, well at least mine he didnt. Have you got to use you heads yet?

Mr. Luos

No. I just picked them up from Byunspeed over last weekend.
Waiting on a couple more things to finish the build.

I had the stage II heads a couple of weeks ago. There were also badass.

On our flow sheets we go to .600". We do flow heads higher for our testing purposes and at customer request.

gunnar what springs do these heads come with, also my car is a 98 with perimeter sytle valve covers, i have a forged bottom end with 6.125 h-beam rods and diamond -2cc pistons, i would like a new set of heads and started leaning at the darts, but i am gonna run thunders t-rex cam and don't think there springs will match good with my combo. plus i only drive the car on the weekend so i would like to run max compression on 93 pump gas.

How do they compare to the AFR 205s?

They have the Patriot Gold Dual springs. Rated up to .650 if im not mistaken.

Gunnar@Patriot

These come with our Patriot Gold .650" dual springs, ti retainers, and Super 7 locks. Give us a call and we will go over the set up and get you fixed up.
