Message	look like this: stock head / stock manif : 171 cfm stock head / ported manif: 211 cfm (i think ported is extrude honed) ------- of course this all depends on the pressure at which it was tested. but if you take the % increase then the pentroofs are 68% and ported stock is 23%. that is pretty good. jefe
