#133981, "head flow"


          

I am just wondering if anyone knows what the flow capabilties of our heads are stock. Or if I should just port it?

um... if you are looking for power gains then you should port it...

I am confused by your post.

Does our stock head flow well? Yes.

Will you make more power with a nice port? Yes.

Sorry for the confusion. I should have been more clear. I am wonderig how much air our heads flow stock (cfm). I know a good port will help but just wanting to know how good they are stock I am building my bottom end then doing my head at a later date since I have an extra head.

I have no idea what the CFM is on our heads, but gasket matching the ports and then cleaning up the rest of the chamber makes a HUGE difference on the butt dunk.
