Ok say you've got a set of 416 heads done with the previously required three angle valve job, what can you actually expect to pickup HP and/or flow wise with the new "any valve job" rule now in effect with NHRA? This is a .357"/.370" lift camshaft. These heads are fresh and I really don't want to go back and redo them if it doesn't warrant the power gain. Thanks.
