You have the heart shape head. I have an 89 and that's also what I have.
So what is it you'r doing? I don't remember ever hearing that term.
What tools do you have? If you have a compressor it's cheapest to just use a air die grinder. Smooth all the rough areas or ridges made by the casting. Smooth around where the valve comes into the port. What's it called...(BRAIN FART..just got home from a 10.5 hour day at work in the heat). The most differance when porting is made when working the outside corner of a bend. I'm new to this to. I have started working my head this last week but haven't had time to get very far. Get carbide bits for steel/iron not alluminum. DUH. Get the shorter ones..I think they are 3-4" long. If there is a swap meet go to it. You may be able to find some there used for cheap. Otherwise they are $15-25 each. You could probably get away with one. I like the christmas tree shape for versatilaty. also get a bunch of 80grit and higher cartridge rolls to smoot it out. hmm... a good tool store will have polishing compound. I was told to use it with a scotch bright pad. They had those there too. You cut the pad into little disks and use them with the grinder. just put a little pollish on the pad.
There are articles out there if you google home head porting etc. And look through the tech pord at turboford.org for info and pics. There's a guy on there named boport that is pretty good.
Good luck. I hope you try it so I can hear if you noticed any differance cause I won't be driving mine for a while.
