i have used a helicoil and it just pulled out due to the aluminum head should i look for a stud instead of a bolt?

the best and easiest way is to use what is called a helicoil. basicaly it is a stainless steel coil like a wound spring with threads on the inside (same as the bolt) and threads on the outside larger than the existing stripped hole. the hole is drilled out clean, then threaded with a matching tap. the helicoil is threaded in with a special tool and you are better than new. actually utilized on aluminum threaded holes during mfg especially in marine industry. auto repairers use all the time to fix stripped spark plug holes.it takes me about 5 min to do one. go to your local service station or buy a kit at auto supply and do it yourself. if this is a one shot deal have it done. youll save money. best of luck. be very careful on aluminum preferably use a torque wrench and only tighten to specified values.

There will probably be a better worded answer, but I would have to say either you get a "Helicoil" to give the hole back it's proper threading, or the hole will need to be drilled out, and a stud with a larger diameter on the head side will have to be used in the hole.
Helicoil, is a product used in these situations, if you are unfamiliar, it basically looks like a spring, and you drill the hole out slightly, and screw in the Helicoil of the appropriate size, and your stud will fit again. I am just not sure if there will be any vibration factor.
the other scenario is that ifit just the top of the hole that it buggered up, and not the entire thing, it may be able to be repaired using a tap?

What bike? It makes a difference. You may not be able to get a helicoil to fit and need a custom end plug made. If its the actual rocker arm, fit a new one. If its the rocker cover to head, either 6mm, 7mm, or 8mm.

Put the head on a mill, and bore out the hole to the heli-coil tap size. Tap the hole, and screw in the heli-coil.
