X, J, or 308?

yes, and a narrow port...like an LA port.lol..

bowl to runner as well, small runner big bowl.

In general one could be correct in saying that a given air flow through a given cc runner.
the high flow through a small port scenario.

thats why i say the LA port IS a high velocity port, to a point and then some..once u start pulling big ported numbers out of it...the port can only get so big, it's small still really when it come to port volume.

which head do you think has more velocity?
An rhs head flowing 244cfm @ 179cc's?
or a factory iron head flowing 244@ 160-165cc's?


So, which is more important velocity or flow? Would the 318 head you ported in the stcky with the [email protected] 129cc ports actually perform better than a head with around [email protected] 179cc ports?
