I need to buy a set of new GM exhaust manifold bolts. They fasten the exhaust manifolds to the cylinder head. It's for a Vortec 5.7L (1999). I can't seem to find the GM P/N on any of the parts websites. Does anyone have the GM part number?

I saw that, too, but it didn't seem right. I didn't think the lower intake manifold and exhaust manifold bolts were the same.These?

I think I may actually go with ARP rather than OEM GM since the GM bolts are prone to failure.May I suggest ARP-bolts.com (a little pricey) or Summitracing.com just in case you are not successful in your search?
Yeah that’s what came up when I entered my vin on gmpartsgiant.comNo, small block exhaust manifold bolts were 3/8"-16 x 2.5" long. Any ole bolts will work.
