okay i have taken a look at my 062s and it appears that the valve stem seals arent pressed in all the way... tricky to get a picture of but just wondering how high they should be?

and what problems could i run into by grinding the bottom of the locks to allow for a cam with .510 lift?

 

I know vortecs have the fat guide boss, but they use the positive valve seals factory don't they? I can't tell if they're far enough down from that picture, even though it is a fantastic high res picture, i'm impressed. I'm sick of camera phone pictures.
I wouldn't grind the valve locks, those are so weeny. (and do you mean locks or retainers?)
Either way, i'd grind the valve boss first.

 

they are the positive seals from factory but could i actually grind down the boss? i havent played with positive seals before? well i thought the locks would hit before the retainers? hard to see without takeing one apart i guess...
