RHS or EDDY

Sportsman, how much work was done to them?
Can you have them flowed?
While the Edel. and RHS head can and will outflow the J head, you allready have port work done to them. Considering your not racing the engine, but simply driving the street, a cheaper route could very well be some more port work done the the J head. This would and should work out cheaper than purchasing ethier RHS or an Edel. head, and having work done to ethhier to make work. Which would include, really everything from start to finish. Valve guide, seat, port work, and how much to work well ontop of 400+ cubes?
