Default Track Performance With AFR Heads

AFR heads have turned in impressive numbers on the dyno. Does anyone have numbers from the drag strip to share with us.

There are many people who have used the AFR 205 head. I assume you are referring to the 225 head. I hope to have some track data on them within a month or so.

I am interested in seeing track results with mainly AFR 205 heads. Since most members are running stock cubic inch engines.
