Polished ports - not ideal, but port shape/size is what really matters
guys back in the 60's experimented with chroming the inlet ports to a true mirror finish, didnt gain anything...but didnt really lose anything either
what I want to know is why is there a blob of what looks like weld attached to the valve guide in the inlet ports, and still using factory cast iron guides? or will they be removed after the porting is finished?
