Product Details

The Cometic C5646-027 is a high-performance Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for GM LT1 and LT4 Generation II small block V8 engines. This precision gasket features a 4.100-inch bore diameter and .027-inch compressed thickness, providing exceptional sealing performance for street and performance applications.

Key Features:

  • Multi-Layer Steel (MLS) construction for superior durability and sealing
  • Designed specifically for GM LT1/LT4 Gen-2 small block V8 engines
  • 4.100-inch bore diameter accommodates stock and slightly overbored engines
  • .027-inch compressed thickness for precise compression ratio tuning
  • Engineered to withstand extreme cylinder pressures and temperatures
  • Embossed sealing beads provide optimal compression and recovery

Cometic MLS head gaskets are constructed from multiple layers of stainless steel, combining flexibility with exceptional strength. The embossed sealing beads ensure consistent clamping pressure around combustion chambers, coolant passages, and oil return holes, making this gasket ideal for both stock rebuilds and high-performance engine builds.

So far great!!

This site is awsome! excellent customer service, lowest rate, Fast shipping!<br><br>I will save this site for my bookmark! %100 must check auto store site.

Great price on name brand parts. Quick shipping. Will use again for my next order of parts.

Amazon pay nice

I got a cargo box from autoplicity. As far as online purchases go to delivery, everything went perfectly. The only comment I have for Autoplicity would be to send out a confirmation email when the purchase is first made. The first communication wasn't until 3 days after I made the purchase.

Best price I could find for the brand new name brand product I ordered. Fast shipping as well.
