My two cents..............
If you're really serious about porting your heads, go & see a performance shop that has an extrusion porting machine....
These things are magic.... You bolt your heads to a machine that uses a compressed abrasive paste that extrudes through your ports etc. You can adjust the machine to give your required flow characterisitcs as you go. You can even bolt bits such as your inlet maifold that you want match-ported.
Also - you don't get that serrated kind of finish that you get from a porting tool too.
Saves stuffing around with a porting tool only to find you're out of whack when you get your head on a flow bench.
Costs $$$, but worth it for the quality.
