Unwanted engine bay heat.

The 1965 Olds Starfire exhaust manifolds are Adequate for my needs.

1970 Pontiac 455 360 & 370 HP Are same size outlets.
1970 Ram Air IV 400 370 Hp same way.
Closer to 425-440 HP actual bone stock no headers RA4.

It's been 3 months. What are your manifolds looking like today?
 
I need to touch up top side.
My fault.
I sprayed down with CRC Brake Cleaner Red Can. Carbon Tetra Chloride Formulation.
Discolored. And removed some.
I had an oil mess.
Mistake learned.

Bottom side of manifilds look great yet.
 
No one here is likely to buy Reproduction 1965 425 Srarfire Exhaust manifolds.
I bought from Fusicks in Conneticut.
Bare spots have not rusted one single bit.
My Grand Prix is outside .
Driven through many rainstirms now.

Must be Super High Nickle Iron used.
