this is some good reading on the upcoming heads i would think that if a man can make 700 hp on a set of cast heads you should easily make the numbers with these they are a step up from the tfs streets and a step down from the tfs a cactings but with the right "smoothing they can be made to flow more than the stock tfs a so with that in mind i think kasse has himself a winner
