small 10 mm head bolt pulled threads from the block HELP!!!
small 10 mm head bolt pulled threads from the block HELP!!! Well my buddy made a mistake and torqued the small head bolts a long the lifters too tight and one pulled the threads out of the block. What now? I saw that people use the time serts. For the bigger had bolts but what are his options for those small ten mm bolts? It was the middle bolt on the row of head bolts on top of the lifters. Any help would be appreciated. It is a ls1 aluminum block with only 30k miles.
Yeah thats what I figured but I saw a lot of people saying they wouldn't work for the bigger bolts and wasn't sure if they would be ok for the smaller ones. Even though they are torqued a lot lighter then the big ones. Just wanted to make sure. Thanks.

Just make sure that the inserts are long enough for your application.

thanks a lot guys. Helicoil worked great. I would agree that time serts should be used last. After all the reading I have done, it appears that if a time sert fail you are really screwed. Would rather have helicoil go, then drill out slightly larger and go with a time sert so at least I have two steps. Thanks alot for everyones help!!!
Really? If your going to lay out the money for Cheesy heli coil why not step up and get a Time-Sert kit? A much better thread repair, especially in something as critical as a head bolt...
you use the heli coil first and if the hole is that messed up then you go with the time serts , you don't want to go too big if you don't have too . Also if you screw up drilling the heli coil atleast you have something to fall back on , what happens if go straight to the time sert and screw that up , no what you going to do weld it up
