valve spring height question

take the heads & springs to a machine shop. they will show/teach/help you i have never had a bad experience if you come to them and ask them to show you what needs to be done.

many times i've went with stuff like that and they say we'll cut the spring seats for $50 bucks or whatever. and you learn somethin. it's a win - win and you know it's done right too

they love to share knowledge... i've never been to a machine shop where they were mean and nasty, generally a great group of people.
