    Default R16TS cylinder head thickness ?

    I'm trying to find out what a standard R16TS cylinder head thickness is. I have a 807-03 engine in the Barn Find.

    Can't seem to find this out anywhere including my 'Intereurope Repair Manual 141'

    Any help would be greatly appreciated.

    Thanks guys

    Phil

    Yep, they're the numbers. I just went through that last week on a head I found to be 91.7

    Trying to figure if I can use it somehow..

    I guess 2 head gaskets is out of the question ! How about thin layer of plasterseen on the piston face and do a test assembly. Soon tell you if anything will hit the valves or not.

    Might be worth asking someone who has worked over the 16 TS engine to find out how far they have taken down a head.
    Renault min head height could be conservative?

    You could try seeing what the clearances are between valves and pistons.
    Set liner protrusion to minimum

    Put some Plastigauge on the piston where valves would overlap
    Cam is probably worn so lift will be less anyway
    Refit head and gasket, carefully rotate.

    Work out clearance from Plastigauge
    Increase protrusion of cylinder liners to max if required.

    Last choice grind a bit from piston crown :-(

    Thanks for the additional comments but lets not get ahead of ourselves, I don't want to hijack the thread. It's just a bare head at the moment. I think it came off a TS motor running Alfa Liners and some flat top pistons with a big cam and valve relief pockets. I have to decide if I use it on the Floride project or just keep it in the spares pile. From memory it was a 1970's race motor and the head was shaved past the normal repair limit to get some compression with the flat top pistons.
