RHS or EDDY

I know the J heads had been redone when I purchased them. Everything was new and the person I purchased them from said there had been $1,200 put into them, he bought them from the guy that done the work. I could see where the porting had been done but not sure to what extent, it looked as if all the runners were smooth. Beyond that I don't know about. They only have about 500 miles since I put them on
