So, I have apparently blown head gasket

[daveymc29]

The oil is full fo water and I will have to determine later why the gasket blew or if I have a crack somewhere. I'm hoping just a blown gasket and wondering what a good rinse for the block would be? Any suggestions? I plan to have the head to the machinist for magneflux and perhaps a bit of truing surface. The engine doesn't have 5000 miles since total rebuild by the boys in Oakdale so I'm still hoping just a blown gasket, clean up, relace and after a few passes with the torque wrench back to normal. 5.5 head. Gasket recommendation?
