valve spring height question

My response cut and pasted from your other thread...

Stick them on and go. It's fine. If you chose to have the heads done properly in the future you can look at it then. I wouldn't care about .040 less installed height. It's got another .200" before coil bind, and we're probably talking about less than 30 pounds more on the seat and over the nose. I'd be much more concerned if the stem heights differed by .040". If they're good - run it.

Additional spring pressure "within reason" is always preferred to less. In the case of a 120 pound seat pressure & 300 over the nose - increasing is not an issue IMO.
