Im re-assembling my heads after thoroughly cleaning them, and with the valve seals off all my valve slide in and out of the valve guides easily accept one exhaust valve. I really have to force it in, and once it gets about 25% of the way through its then easy to slide in. Same with pulling it out, it starts to come out easily, but when I get toward the end its a bitch to pull out. Even with oil on it, I have to force it and turn it to get it in and out
Sound normal or do I need to replace that valve?

Your local machine shop can check it or you can put it in a drill and spin it. A good visual inspection should show you signs of wear in only one spot on a section of the valve and not others. Alot of times the head will mushroom a bit. You can use emory cloth to clean it up. Better to do it now. Itll cost more later. New valves run about $14-18 a piece roughly.

Roll the valve stem on a piece of glass. If it's bent, you'll know it. That's how to check push rods, too, BTW.
Most likely, there's a raised ridge around the locking groove; that's really common. Use a fine file to gently remove that ridge.
When you force it in and out of the guide, you're shaving off guide material. That's a bad thing.

Yeah the shop told me the same thing dammit. Sure enough, I shined a flashlight down the guide and its marred up a bit... as a matter of fact several of them have some grooves so they recommended I bring them in and have them clean up the guides with a small ball hone.

cylinder head specialist knows and most regular gearheads don't. In most
cases, cylinder head guys are under appreciated and under payed....perhaps
why most of the GOOD ones I know are always kinda grumpy....
