Does anybody know of any problems with ceramic coating combustion cambers & the front face of the valves I have a 2.3 I4 that I am turboing The problem that has been pointed out to me is that the combustion chambers are large which does not leave much meat between the chambers (bores) & could anal with the heat & loose its grip on the head gasket which is about 6mm between the bores I am looking for about 400bhp but now worried about this, but ceramic coating should fix it (or not) but is it prone to flaking etc

IAN

PS the engine is built so I would have to take the head off & stripped to get it done but I dont want to damage the head as its all been ported.
