Product Details

The Cometic C5409-040 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for AMC 390 and 401 Gen-3 V8 engines equipped with Indy cylinder heads. This precision gasket features a .040" compressed thickness and is designed for a 4.380" bore diameter.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior strength and reliability
  • .040" compressed gasket thickness
  • 4.380" bore diameter for proper cylinder sealing

Cometic's MLS gaskets feature multiple layers of stainless steel with elastomeric coatings that ensure maximum sealing performance.

Autoplicity was great, I ordered my springs late Monday night and I received a shipment order confirmation number early Wednesday. So basically 1 business day and my order was out the door, pretty impressive. Can't wait 'till it gets here! Thanks Autoplicity!

Awesome vendor, super fast shippng and the lowest prices anywhere. Highly recommend and will use again.

Best price I could find after hours of searching, I recommend 100%!!!

They had the best price on a hitch I was looking for and the shipping was fast also. The hitch was shipped bare except for taping the box of bolts to it thus leaving the hitch open and chipping the paint/powdercoating in quite a few places which I had to touch up before installing.
