I need to get head bolt threads repaired and im looking for a machine shop that uses time-serts in the tri-state area.

 

Depending on the block you may not want to use them. Why don't you want to use heli coils. The size of the inserts requires a miuch larger thread to install and the block gets thin. Use heli coils with extra long inserts not the standard length. the other option is to use oversize studs if there is something available for the block your using.

 

I just want something that i wont have to worry about. Its a turbo motor so its going to be abused
