You lost coolant is that why the new head gasket? Are you still loosing
coolant? What reason did the Mechanic give you for the head gasket failure
and the need to change it in the first place?

Hmm!! Too small? As in the the valves were from the earlier head - 1.56"
inlets, 1.344" Exhaust? Someone correct me if I'm wrong as my knowledge of
later cars is limited, but I thought the only change in valve size came in
the 18V motor that upped the inlet valve to 1.63" or something, and they
went BACK to 1.56" later on in the MGB life to regain torque....? I would
have thought a 79 should have the smaller inlet valves -?

If that statement is correct then your cylinder head should have the smaller
of the two types of valves, therefore what the mechanic says doesn't hold
water. The valve seats need to be cut specifically to fit a certain valve
size. I find it really hard to believe that you conked out on the motorway
some time AFTER the head work as I presume it was running fine prior to
this?. With incorrect valves in there, the motor wouldn't have run properly
from the first moment you turned the key... I would suggest something else
went wrong, he stuffed up the head gasket install etc, or you blew another
head gasket, you are losing water & overheating etc.

What did this guy bill you for? New valves etc?

Anyone else?
