Product Details

The Cometic C5641-036 is a multi-layer steel (MLS) cylinder head gasket engineered specifically for GM and Mercury Marine Gen-IV big block V8 engines with a 1050 cubic inch displacement. This precision-manufactured gasket features a 4.600-inch bore diameter and a compressed thickness of .036 inches, providing an optimal seal for high-performance marine and automotive applications.

Key Features:

  • Multi-layer steel construction for superior durability and heat resistance
  • 4.600-inch bore diameter accommodates Gen-IV big block configurations
  • .036-inch compressed gasket thickness for precise compression ratio tuning
  • Includes two slotted lifter valley bolt holes for proper engine assembly
  • Designed for GM and Mercury Marine 1050 Gen-IV V8 engines
  • MLS design provides excellent sealing under extreme cylinder pressures

Cometic's MLS gasket technology uses multiple layers of stainless steel with specialized coatings to create a superior seal that can withstand the demanding conditions of high-performance and marine environments. The gasket's construction allows it to conform to imperfect sealing surfaces while maintaining consistent clamping pressure across the entire combustion chamber.

These people are just awesome! I got my Thule Bike Rack for a fraction of the cost compared to everywhere else. Shipping was very fast and cheap but when I received it there were a couple of missing hardware parts. Thule wanted to make me ship the whole thing back. Rob Fratu of Autoplicity took control of the situation and got Thule to ship me the missing parts and some extras, all within a couple of days. I cant remember a better experience with a retailer.

Fast good prices

Cheapest priced ARP head studs on the internet. A++ I will definitely do more business with Autoplicity.

They had what I needed, No hassle ordering. and it shipped fast.

Great price, good e-mail communication and fast shipping. Positive experience with Autoplicity so far.

Easy to use web site. Quickly found what I needed. Smooth check out and SUPER FAST delivery. Couldn't ask for a better transaction experience. Bookmarked and for sure "GO TO" for next auto parts search. Thanks Autoplicity

Could not find the part I was looking for at any other 4x4 website. Found it here and it was cheaper than almost every other place. Since I saved some I went ahead and paid the extra for 2-day shipping and still came out on top price wise. Definitely will be checking here again for parts for my Jeep!

Best price I could find on Moog Suspension parts.

Placed my order for my K&N CAI on saturday, but didnt have enough cash so the order finalized on sunday morning. Autoplicity provided excellent service via phone and I should be receiving my CAI later today!!!! Super Stoked. Thank you Autoplicity for providing good service!!<br>Will buy from this site again!!

Wow super fast shipping and I ordered over a holiday weekend. Will be doing business with this site again soon.
