Chevy 409 425 HP Grade 8 ARP Stainless Steel Exhaust Manifold Bolt Kit

This an exhaust manifold kit for mounting stock manifolds to the heads on your Chevy 409 High Performance 409 H.P. & 425 H.P. V-8 engine.

These bolts are ARP Grade 8 stainless and come with a polished finish.  These bolts are rated at 170,000 psi.  The kit also comes with our thick stainless washers.  These bolts are much stronger than the stock bolts. 

These are not for the standard 348 409 Exhaust Manifolds.  We have separate kit for that.
