Re: Head Bolts or Studs ?
I would use the factory torque to yield head bolts before I would use a Chinese anything. I used ARP head studs in my 406 build and in a high compression pump gas 555 due to the studs ability to provide better clamping for my race gas motor and not to pull the threads out of the stock small block's deck. The rest of the motors I build I use head bolts as they are easier to install and with a low compression pump gas motor it is adequate for most street strip applications.
If you use studs you have to hone the block with the intended studs installed and a torque plate that meets the length of those studs (most block torque plates are just two inches thick billet aluminum). This is because the stud doesn't distort the block the way a head bolt does.
For a blown application it would depend upon the amount of boost you intend to run. More than eight pounds of boost and I would start to consider studs over head bolts.
Fasteners are a consumable in an LS-x engine. Don't go cheap as you may regret it. Depends upon whether you like replacing head gaskets and risking hydraulic shock to the motor should you blow a head gasket with out knowing it.
