Heck we all gotta start somewhere! I've ground my own heads using quality guides and stones and it can be done. It's interesting and fun. I've even done the valves. Got in there with die grinders and tried my hand at the 'port and polish' thing to. When the dust had settled, many heads down the road, I determined it was a job best left to a proffessional! Haven't touched a valve seat for years now.
