It over heated very very badly know it won't start but it has spark, could it have jumped time somehow, it has compression

Remove all of the spark plugs and check the each cylinder's compression with a gauge. Record the results on paper. The results may indicate that the head gasket blew. It's common in these situations for the aluminum head to warp, valves to get damaged, and the head gasket to blow.

Cylinder Compression Pressure:

Standard: 184 psi
Minimum: 135 psi
Max. variation between cylinders: 28 psi
