Funny, I'm doing the exact same thing with my A14 cylinder head as we speak. I tore it all apart, took all the valves and studs out and started porting/polishing it. The best way to match
the header and intake with the ports is to grab a used intake/exhaust gasket and see where the gasket either wasn't compressed around the port, or where the gasket is blackened. I'm using a
grinding tool in a drill to port it out first, then use 3 stages of emery cloth (rough, medium, fine) to work out all the imperfections and create a beautifully smooth and almost mirror
finished port. After that I use aluminum polish and hand polish until it really is like a mirror. It's important to get the exhaust as shiny and smooth as possible, but it's not as important
with the intakes. So far I have one exhaust port finished, took probably about 1.5 - 2 hrs, but it looks great! I used this same technique on my GX intake and every time I take it off, it
still looks like a mirror. Anyways, good luck with your head. I'm going to have the machine shop put in bronze guides, new seats, oversize stainless valves, etc. Should run pretty good after
it's done. See ya later!
