It rather goes without saying that when replacing the guides, you should also grind the seats and valves. No point in all the work otherwise, at least in my experienced opinion. You probably don't absolutely have to but it would be best to do it and get it done right at the same time.
As far as replacing the guides yourself, my fear is in cracking the block which is why I always without fail have it done professionally. I can do nearly anything needed on a car and have done so all my life but I draw the line there.

De-carbon valves and valve pockets. Wire wheel is good for valves and 1 inch knotted wire brush in a die grinder or drill works great for pockets. Mic your valve stems in the wear area. Make sure they are in spec. After installing the new guides check the valve fit in the guide. If in spec, grind valves to angle. Grind valve seats (3 angle job) and lap valves to seats. If you don't have the grinding equipment, find somebody who does. You can bring them the valves but they'll have to come to you to grind the seats unless you take the car somewhere to have the job done. You want your valve seats concentric, so you're going to pilot the grinder off the new guides. Do the complete job once, and do it right. Saves money and aggravation down the road. PB
