I bought new valves and when I received them the exhaust valve stems where longer then the ones I pulled out. Is this an iassue?

1.8

What is the overall length of your new valves and what is the overall length of your old valves?

Old ones 3 and quarter new ones about 4 inches. Its not much but enough to worry if you don't know these things. Wish I could send a pic, I don't know specifics on them. Its exactly the same size front where the keepers sit. Well same size as a keep I guess is say. Lol it says in the book the old ones where 3.8. Can't find what these new ones are. But like I said its the height of about the keeper area.
