I hear you Posted by jak [Email] ![]() ![]() In Reply to: head porting, exhaust tuning, MS, Wed, 4 Aug 2004 10:48:12 Members do not see ads below this line. - Help Keep This Site Online - Signup |
on an NA engine you would have the ex manifold runner bigger than the port to help keep gasses moving out & to avoid reversion due to high overlap cams
on a turbo I would probably opt for gasket matching but the before mentioned method would be worth a shot it couldent realy hurt anything
some headers have a weard cone point tward the port at the beginning of the runner to do the same thing I mentioned above
on the intake side I agree on having the port narrow somewhat before the bowl than opening up the bowl also never lower the floor of a port only raise the roof & widen
my intake ports
take care
JAK
