Athena Racing 330 series Cooper Ring cylinder head gasket.
For specific high horsepower applications, engine performance can be significantly improved by using Athena Cooper Ring gaskets, that are supplied with INOX steel ring. This technology outperforms conventional fire ring solutions.
Cooper Rings are oversize (also fits for oversize bores).
Part number: 330012R
Gasket thickness: 2.00mm
Bore size: 84.50mm

|
Reinforced material |
Asbestos free composite raw material OE approved |
|
Stainless steel ring (AISI304) |
Separate stainless steel rings assure maximum sealing around cylinder bore also on NOS and/or turbo charged engine where boost is over 2 bars. No head and block machining required |
|
Silicon beading |
Silicon-based beading is applied on critical areas to improve sealing around all cooling water and oil passages |

COMETIC MLS (Multi-Layer Steel) Head Gaskets provide maximum sealing performance for today's high output engines and require no sealants. MLS gaskets are ideal for both aluminum heads to aluminum blocks and aluminum heads to cast iron blocks. They can withstand the shearing force created by the two materials. MLS gaskets have increased strength because they are comprised of multiple layers of stainless steel; which also creates the ability to rebound and resist corrosion. The outer layers are embossed and coated on both sides with Viton (a flouroelastomer rubber based material that is heat resistant to 250 C/ 482 F). Viton is designed to meet the demands of a variety of harsh sealing environments, load conditions, and surface finishes. The center or shim layer is uncoated stainless steel, which can be varied to accommodate multiple thickness requirements.

Set includes:
1 cylinder head gasket (87.50x0.60mm)
1 valve cover gasket
6 intake manifold gaskets
6 exhaust manifold gaskets
24 valve seals
and etc.
