Sorry but i do not know the answer to your question; but, if it is going to sit at all with a bad head gasket, change the oil and put oil in the cylinders so it does not seize. Anti-freeze sitting in the cylinders and in the oil wreaks havoc.

Good luck, hope you get it going without a lot of trouble and expense!
