Valve stem seals

Y R
What seals do you suggest,??. I am confused buy this. I don't want to get the guides machined, they are stoc factory. I just want a good seal.
Thanks

I’m not sure why all the love for a cheap, crap valve stem seal. I understand that you have them, but so what?

If the heads are still apart, take them to a shop and have them machine the top of the guide for a positive seal. It may already be done, but you need to post a picture, or measure the OD of the guide.

Ring seal today is nothing like it was. Running a cheap seal like that just isn’t worth it to me. I mean, look at the junk **** Chevrolet sent out...a square rubber o ring at the top of the valve, just under the keeper. Worked half assed back then, but no self respecting machinist or engine builder would use those today (I hope they wouldn’t).
