Head bolt length

[eman2289]

Can some one let me know what the overall length of oem headbolts for a 7mgte are. If you could also tell me the length of the threads, it would be greatly appreciated.

EDIT: sorry, i just realized this should probably be in the 7mgte tech section

Family Guy episode:

Stewie at ball game to kid in seat next to him: "I'll trade you my ice cream for your plastic bat"

Kid: "OK". Hands over bat.

Stewie, after keeping ice cream and smacking kid with bat: "Now, what did we learn?"
