why or why not? if two valves of the same size are run, one with more area shrouded over the other, the less shrouded valve should flow better, or do you not agree?
Mcsa.(Minimal Cross Section Area) If it is at the valve at say .400 lift on up, then yes less shrouding is a good idea. IF the Mcsa is some were else in the port. (most likely at the ssr)well your not going to get any more air through that port by un-shrouding it.
