hopin my teeners not fried

comin home fro car show on sunday, stopped for a break then decided to smoke the tires, as usual in my idiot state of mind it hit 7000 rpm. carried on then a few miles later, god awful noise and smoke, still ran so i limped her home, pulled driver side valve cover cause so much oil was coming out of breather, n0 7 looked real hot and smoky, pass side n0 2 both push rods slammed through rocker arms. should i just replace them and see how see she runs or investigate no 7 more? the no 7 plug looked fine!:oops:
