The MHG us ynneccesary for stock. The stock toyota HG will hold up to a lot of boost, for a long time. The important part is keeping the motor cool, not overheated, proper torque on the bolts, And good gas. A stock toyota headgasket and arp studs torques to 110 ft lbs will hold up to 350 rwhp, And maybe more. Detonation is what kills the headgasket. And yes, Once the repairs are done, You wont need any work for a long time. Itll be good for a while.
