I pulled the aluminum head off of the daughters old Camry (5sfe, 4 cylinder) and may have to purchase a reman. head because of some pitting I can see from one water jacket that extends close to the fire ring. However, first I'll take it to a local machine shop and see what they recommend.
If I go local I will not be getting a full valve job but asked about setting the clearances and he said he would tip the valves as needed.
I know this engine has shims and buckets so I thought the correct method was to replaced a shim if the clearances go out of spec.
Tipping a valve is probably cheaper but should one be concerned about removing any hardened coating on the stem that might expose the non-hardened metal; which might make premature wear? Perhaps that isn't a concern unless they are removing more than a few thousands but I don't know.
Anyone that knows more about this subject I'd like to learn if I need to be concerned if the valves are being tipped.
