I am selling my AFR 180 heads. They have been fully CNC'd by TPIS, then the were further hogged out by Fonse Performance. Thave been flow benched at a little under 300 CFM. *After TPIS's CNC work (before Fonse Performance CNC work) they were 187cc on the intake side and 54cc on the combustion chamber.
They have been proven to work excellent under boost, but would also make a great upgrade to an N/A or nitrous setup.
The heads have about 20,000 miles on them and are complete minus the rockers. They are in excellent shape.
