Hers is some Small block J heads I did myself. The intake ports and bowls are not polished but left as is by the cartridge rolls. Combustion chambers, exhaust bowls and exhaust ports are polished. Intake side is gasket matched and I removed a little of the pushrod pinch. I did not gasket match the exhaust side but by removing the cast rough finish it did enlargen the port window slightly. But I've exited the car hobby recently. These are just stored in my house now. I rounded and contoured the valve guide bosses. Steve Duclich did an article on his porting of J heads around 2001. He had IMPRESSIVE flow numbers but he really removed ALOT of the valve guide boss which I did not even begin to do.
