Started the Z up after a heads/injector/header swap and it ran pretty well for 20 min until coolant started pouring out of the passenger side head (forgot to plug the coolant temp sensor hole). When I tried to crank it after I plugged the hole, the driver side valve cover gasket blew making a loud popping sound. What could cause this? I figured if the gasket was bad it would start leaking, not blow up.
