Its not really that bad, i did alot of reading before i started and its actually fun. Will be very time consuming.
When i first took the grinder to the head, i didnt have a feel for it yet, i was like "**** this is going to be harder than i thought"
then after i got to doing for an hour or two, it got easier.
Kind of hard to explain, but you can tell what needs to be done to the ports, i feel it with my finger and just make the stuff smooth and no sharp edges.
If you ever thought about trying it, try it, its fun
