Question rebuilding engine, porting help

My car 1988 NA GXL

First question before I go farther into it.
Can you port a six-port NA engine and still have the fifth and six ports functional using the sleeves and actuators?

My 6 ports on my old s/c motor. I always wondered how well this port would work combined with function 5&6 ports, bridged auxillaries and pineapple sleeves on a n/a project. I have a friend with this port on his s5 na and it seems to have a very nice wide poerband and a great idle.
