BB Chev valve stem seal question....

Thanks for all the help, Guys! I'll likely either go with the OS 450's, or the small block o rings. The ports are dry light grey, no sign of oil but just trying to be cautious while I've got the opportunity and the race springs are off. I'm using light ones to break in a new cam. Good time to add a bit better seal for now, then will machine the bosses next time the heads are off the engine.
