Diy Valve job

The idea that machine work is some genie in a bottle is simply insane. You can certainly learn to do it yourself. I do a lot of my own cylinder head work. I've never posted it on here and never will, because I use old school methods such as stones and diamond sharpeners.
If it works it works. I posted mine here, but if anyone wanted to see them they can go to my u-tube channel and watch them. I did the low dollar 318 heads on this site and over 4 years later they are still taking a pounding and most importantly - I'm happy with them! Cost? new exhaust valves, valve seals and new eddy springs and throw in a few stones for porting and maybe 125 bucks total.
