head bolt measurements
 

Good afternoon
Does anyone know what the length of the head bolts should be for a 19j engine ?, I've just done head gasket and put a head on that I had pressure tested and skimmed, and when I was filling the coolant system up, coolant was coming out between the block and the head at he back above the starter !, I'm going to get new bolts on Monday, but just wondered if anyone knew what the correct length (pre stretched) should be
Thanks Dave
