Valve job with head gasket replacement?

No merit to it at all, I have driven a blown head gasket on a 340, blew it between #2 and #4 piston, blew a little of oil out the dip stick and smoked out the left bank, drove it for 3 t0 5 miles back in 1985, Drove it another two or three years after I changed the head gasket (hard) :burnout:
