Is there a specific intake manifold gasket kit for peanut port or just use standard oval port gasket?
Was looking at fel-pro # 17340 but port size is std oval not peanut. Any problem here?
Thanks in advance.

Those will work fine. Don't worry about the openings being larger.
Note: If you have a large oval intake, even with peanut heads, you'll need to use large oval intake gasket.

You have more choices. Below are also for peanut intake, peanut heads:

Here's the latest for peanut intake and heads: it has steel core.
Felpro 1212S3

If you have the electric choke, and want the exhaust crossover's closed for a little more performanced (less intake heat)

Sb thank you, just wanted to get it right, wasn't sure if larger gasket created unwanted swirl.
Manifold is edelbrock # 2161 peanut sized dual plane.

Swirl ? Like from creamy to chunky ?

that sounds like an oil problem!

Nope. Peanut Butter Oval Ports. It's NUTS.
