Product Details

The Cometic C5721-062 is a premium Multi-Layer Steel (MLS) cylinder head gasket engineered specifically for Buick 3800 Series II and Series III V6 engines. This high-performance gasket features a .062" compressed thickness and is designed to accommodate a 3.840" bore diameter, making it ideal for stock and modified applications.

Key Features:

  • Multi-Layer Steel (MLS) construction provides superior sealing and durability under extreme pressures and temperatures
  • .062" compressed gasket thickness for precise head-to-deck clearance control
  • 3.840" bore diameter accommodates stock and slightly overbored Buick 3800 V6 engines
  • Compatible with both Series II and Series III Buick 3800 V6 engines
  • Engineered for enhanced combustion sealing and resistance to blowout
  • Suitable for forced induction and high-performance applications

Cometic's MLS gaskets utilize multiple layers of stainless steel with specialized coatings to ensure optimal sealing between the cylinder head and engine block. The design compensates for imperfections in the sealing surfaces while maintaining consistent clamping pressure across the entire gasket surface. This gasket is compatible with RHS (Racing Head Service) cylinder heads and is an excellent choice for engine builders seeking reliable performance in demanding conditions.

Order # 26695 I ordered an EGT and a gauge pod. It showed up at my house 4 days later exactly as I had ordered it. The Prices are unbeatable!

Shipping was fast and without damage and the price was great.

seemed a bit hard to find products, but the prices were great and delivery prompt

This is the first time I've ordered from this site, but things look good from what I can tell so far. They had the parts I was looking for (including a fairly specialized racing part) for a price slightly lower than other places I had looked, and my order shipped the next business day. At the time I wrote this, they were also offering $5 back on my order for writing a review. ;-)

Thanks for you swift respond for the email and your accurate information and i hope to deal with you again

Great prices and super fast shipping. Good job.

The correct product that I ordered, and easy to find through there web site.thanks

Cheapest prices I found online! Ordered at 4:30 on a Thursday afternoon and had 'em waitin' on my doorstep by SATURDAY!
