906 heads

earthmover said

what do you guys think of the 906 heads???? i got a pair from a guy and was told that they flow pretty good..ported he says that they went 300/2xx in/ex does this sound right for the iron head????? i plan to put them on the 400 that will go in to the dart if i dont sell it...along with a nice solid or small roller over time ...just looking to see if the #'s sound about right...

How much lift are you planning to run ? Some people brag up the hi lift flow but guess what , it's only there for a split second , it sees all the low lift flows TWICE , on the way up and on the way down. Also depending on the head you can make real good hi lift flow and ruin the low lift numbers which are just as important because you use them twice ...

Flow at .700 on a 906 is sort of useless because who is going to build something with 906 heads these days using a .700 lift soild roller ?

No offense to anyone was meant ...
