i think that by the time a guy pays a real pro to rebuild iron heads properly at a good shop, and then pays a real pro to port the iron heads, even with stock valves so to keep it cheaper, it ends up a total waste for money compared to the cheaper alumnum hedas for sale.
also, at work we will not even port any heads unless we do a flow test after to prove the flow, and that costs more, to which guys dont want to pay for either.
dont waste your money.
i think the only way to port iron heads is to do it yourself with the dodge templates you can buy.
