Yeah, you're supposed to get new headbolts anytime the head comes off if you're using stock ones. Maybe you should look into some ARP studs the next time you pull the head, just for some added security. Also, I'm not sure about Mugen gaskets, but the torque spec for aftermarket gaskets is usually higher than stock ones. In other words, the manufacturer may specify a higher torque spec than your Helm's manual would for a stock gasket. Before you go out and get a new gasket and head bolts, doublecheck if Mugen has a different torque spec than stock, and retorque your headbolts. Evenif the Mugen specs are the same as stock, go ahead and retorque your headbolts anyway, and see if it helps.
