I've got a set of Patriot Performance Stage 2 heads that I would like to sell or trade, Patriot P/N is 2033. Looking for a set of AFR’s with some cash on my end. Heads were sent back to Patriot last year to be freshened up before they were bought out by Promaxx Performance. Patriot replaced all valves, springs, retainers, locks, and performed a 5 angle valve job. These heads are essentially a new set of heads. Heads have not been installed since the rebuild. Still in the plastic and Box. I was going put them on my new engine project but have found out that they will not work with my new motor set-up. Price is $ 1100.00 OBO plus Pay Pal and shipping. According to Patriot these heads flow the following Intake 304 cfm @ .600 lift, Exhaust 229 cfm @ .600 lift. I will send sales brochure with head data to buyer. I have listed the specs of the heads below. I can e-mail pic’s to anyone that is interested.
