And again, yes, ONLY on intake valve stems.

Take off the exhaust valve stem seals before the stems/guides wear out 
from lack of lubrication!

Guides are made to have seals, as the same guide is used for intake and 
exhaust, with seals on the intake guides only in Corvair applications.

Typing on your phone? Autocorrect made it hard to decipher.

He did the valve seats, guys and valves for me on the cents.  When I picked them up he told me that he had installed seals on the exhaust valve guides.  I told him I didn't think that Turbo exhaust valve guides took seals and I was concerned about the heat that the ease guides are subject to.  The guides are new.  They were ordered from Clark's and all the ones that have snap brings to keep the guide from falling into the combustion chamber.  My friend told me that the guides looked as if they were made to have seals.  He told me that to the best of his memory early Corvair engines had Capps on the exhaust valves that prevented them from being bathed in oil.  Right now I'm not sure what I should do should I leave the seals on?  If I do do I run into any issues?  Am I better to take them off?  Many thanks in advance for any adv
