they flow the same as your typical 241 or 853 heads but with that you gain some added CR. they will raise your CR up to about 10.7 to 10.8 and with that much gain in CR youl likely see a gain of possible 25hp. now CR is nice when using large cams. best thing to do is get a set and add 2.0 valves in them and youll be set ---

for 150 adding valves wouldnt be bad im lookin into a cam in the future have a few other issues that need addresed. how would you cam your selling and these heads with 2.0 valves work out ---
