318 head porting for the average joe

Thanks man, this thread will help me for sure.
Post some pics of the tools you are using if possible.

I took my heads to a shop just for cleaning. I'll pick them on monday.

I have a question - I'll run the 2.02/1.60 valves that I already have. Should I cut the new seats before starting any porting or I can cut them later? My plan is to start polishing the chambers and then cut the seats, so I wont run the risk of scratch or damage them.
