Studs or Bolts

I am forging my LS6 block for forced induction. Are studs for the mains a necessity or will a good set of bolts do? Planning on about 7lbs boost.
thanks

i went studs just for the fact if i ever switch heads i don't have to clean head bolt holes and studs arent that much more money then the arp head bolts.

The stock bolts work fine.

Studs WITHOUT QUESTION..

Its inexpensive in relation the bolts, and the added strength is much greater. The last thing you want is those main caps moving around.

Plus, no one EVER keeps it at low boost. No matter how good the intentions are.

Always do studs - and this staying @ 7 PSI of B@@ST! Well let's just say "DON"T" fool yourself

You will want more and you will get more and you will be glad you did studs

Thanks,Matt

Since the block and main cap are aluminum you can only provide the clamp load that the softer material threads can handle.
The steel bolt or stud will have a much higher tensile strength and pull the threads out of the block at the same torque level.
