the r motor has a decent port from the factory..port matching is the only real thing you should do..its usually very expensive..because its all labor..heads usually a grand and up..intakes manifolds usually done when you take in your head..as far as the block goes..i never seen one ported..lol..but they do massage them..take out all the casting imperfections so water will flow better and oil wont build up..but that also $$ hope this helps..honda ports are close to perfection..
