I have been thinking about valve guides lately. I want to have new guides installed on my head. I am getting a serdi valve job with new valves, but I'm not sure which guides to buy and what else is involved. A local machine shop will be doing the work. So far I have new valves and new valve seals. I have not removed the old valves. I am rebuilding for reliability not performance. I planned on using the stock springs and keepers with a stock cam. Which guides should I buy? Some are oversized others don't seem to be oversized. I assume with new valves that I would need at least 1 new guide installed so I figure I may as well have them all installed. I have also heard about sleeving the existing guides. Is this a viable alternative? Any help would be appreciated.
Thanks
Scott
