Maximum quality maximum performance and minimum pricingpromaxx maxx series sbf cylinder heads take affordable power to the next level. Anybody here run the promaxx former patriot heads.

We previously ran these promaxx heads on a smaller 347 stroker but with 210cc intake ports that flowed over 320 the heads were better suited to a larger more powerful stroker combination.
