AFR 205's and 2 sets of pushrods for sale For Sale:
AFR 205's (AFR 1510's).
These heads have about 250 miles on them, which included Speed Inc., tuning dyno pulls. I physically drove the car long enough to get it home to Elgin from Schaumburg, cruised it once or twice, then the trip back to Speed Inc., in Schaumburg from Elgin. That's all the mileage they have on them.
New, these heads are:
Speed Inc.: $2,205.99
Thunder Racing: $2,189.00
Texas Speed & Performance: $2,182.00
T-Byrne: $2,424.99
TTP: $2,207.00
That averages out to be $2,241.80.
I'm asking $2,000 or REASONABLE offer! I would prefer to sell locally in the Chicago/Milwaukee areas as I really don't want to have to send these out. I think I even have a set of new GM headbolts that I can include if you aren't using ARP reusable headbolts. HEADS HAVE BEEN SOLD!
In addition, I have two sets of pushrods:
The first set are CompCam #7638, Magnum 7.400" pushrods. These have the same mileage as the heads.
The second set are CompCam #7795, Hi-Tech 7.375" pushrods. These have only a few dyno pulls on them.
Either way, both sets are perfect and in their original boxes. Asking $100 for each set.

I swapped them out for Patriot heads. My original intention was to do the AFR's and a blower as the AFR's make a great blower head, but then I had a youngin come along which changed my spending priorities some. 
I decided to stay N/A as it was cheaper and the Patriot's were a better choice for N/A.

1) AFR's aren't torque friendly in N/A applications. This was apparent by mine only making high 370 - low 380 some foot pounds of torque while making 403rwhp. Normally I wouldn't be that concerned, but in a 4,000+ pound GTO (with my fat **** in it), I need torque. After two cam changes to see if it was cam related, the only other option was the heads.
2) AFR's have a 66cc combustion chamber. This effectively keeps compression just above stock levels. The Patriot's have a 59cc combustion chamber and me having the heads milled .025", therefore increased my compression ratio (Approx 11.3:1), which in turn helps cure problem #1 as my torque went up to 400 foot pounds on Speed Inc.'s dyno while doing 405rwhp.
If I had been able to stick with the AFR's, then done a procharger on top of it, the combination of the Procharger and AFR's would've made up for the torque AFR's N/A torque loss.

Why not just mill the afr heads down to increase your scr and regain your torque just like the smaller cc patriot heads. Plus, the afr's have smaller runners which would be conducive to added increased torque over the patriots with everything else equal. Use some thinner gaskets and gain even a little bit more lowend.

I didn't want to mess with the AFR's in case I was financially able to change later down the road and add that procharger.
I was sitting on them hoping that I could even add them to a TrailBlazer SS in a few months, but I was let go from my job last Friday.
Which is the impetus as to why I'm selling them instead.

I understand your reasoning now. Good luck with finding a new job. You wouldn't take $1800 for the heads, would you?
