I have found a couple ideas on bolts (hardware) for my 455 build.

Any thoughts on these or others.
As I have little or none.

 

ARP, although more expensive, have a proven record and are hardened steel.
I wouldn't trust foreign Stainless Steel el cheapo bolts on a lawnmower, especially if they have to be torqued!
And drop one of those non-magnetic SS bolts down a intake port, accidentally!

 

I would check Fusick first. Their quality is first rate.
