Shawn, I have a set CNC ported irons with the intake and exhaust ports smoothed, Ferra valves, 1.77/1.55 set up for hyd. roller. TD roller rockers 1.65 . They also have receiver grooves for orings, thou I have them installed with steel shim gaskets. There still on the car and I should be removing them within the next few weeks. I see your in Jersey, if you wanted to see them in person to see there are no issues it could be arranged. Would like to get a $1000.00 for the set up Mike
