300.00 , bare castings , race ported by Champion , have larger intake valves than standard castings .
These are the first gen GN 1 "R" heads ,were on my car for 5 years , one head has small cracks on the outside row of bolt holes, can be fixed by Champion for cheap , I called and spoke to Tom about this , the other head looks ok ,
New, ported 'R" castings are 1900.00 , these can be repaired and complted for less than 700.00 . If you run them on a 8 bolt block they should be fine .
