Default 1/2" head BOLTS
So I have a block that was machined for 1/2" studs that is sold now. I have the ARP 1/2" head studs but the guy is going to run a stock setup and doesn't need studs.

Anyone aware of 1/2" head bolts?

Grade 8 bolts from the hardware store should work. Torque Specs are available online.

I've uses Grade 8 bolts for replacement head bolts on other projects as well. Wouldn't be at all afraid to use them. Just use a hardened washer and assm lube and you should be good!

That's something the machinist that drilled and tapped the block should know.

This...unless you know exactly threads that are in the block, it's pointless trying to buy anything, studs or bolts.

If its a 04' newer block you could possibly use a Ford Cleveland head bolt set from ARP.
