rob, i had a look on the website but cant find prices for cylinder head gaskets and thermostat.
as you might of read my car had overheated 
getting it checked out tommorow but it looks like the heads will need skimmed and either the fault was the thermostat or the radiator :? so i just need some ball park figures and youll be recieving a phone call tommorow probably once i find out the damage.hopeing to get the car back on the road next friday if all goes well.
