Hello guys
I would help my godson who open recently a cylinder head,crankshaft engine block etc repair shop.He ask me for some technical catalogs for cylinder head maintenance(how much can be take from initial thickness,how much is allowed to came out a valve from cylinder head,etc)
I hope I made myself understood what I'm interested.Some of this data can be take from reparation manual of each manufacturer but information are weak and I thought someone can help me with some information.
Thanks in advance

the information you're looking for is scarce
people dealing with rectified and repaired cylinder head (turners) may have some information

I know what you say but same time information in this domain are sometimes confuse and not all time right,by other side he was able to get from local Peugeot dealer some documents,about how much is allowed to rectify a HDI cylinder head,so seems they have so kind of documentations
