Who Are Athena?
Founded in 1973 by Giovanni Mancassola, Athena began as a small workshop in Italy and has grown into a global leader in gasket manufacturing. With over 550 employees and operations spanning Europe, Brazil, and India, Athena supplies both OEM and racing-grade components to manufacturers and tuners worldwide.
Their reputation is built on technical innovation, rigorous testing, and a commitment to continuous improvement - making them a trusted choice for everything from daily drivers to full-blown race builds.
Why Upgrade Your Head Gasket?
Standard head gaskets are designed for factory tolerances and moderate power outputs. But once you start pushing more boost, higher compression, or aggressive cam profiles, the demands on your engine’s sealing system increase dramatically.
Here’s why an uprated head gasket like Athena’s Multi-Layer Steel (MLS) or Cut Ring designs becomes essential:
- Higher Pressure Resistance: Ideal for turbocharged or supercharged engines where cylinder pressures exceed factory limits.
- Improved Heat Tolerance: Prevents warping and seal failure under extreme temperatures.
- Superior Sealing: Raised beadings and elastomer coatings ensure tight seals around combustion chambers, oil, and coolant passages.
- Durability Under Stress: Athena gaskets undergo stress-relief processes and feature gas stopper technology to maintain seal integrity during high RPM and thermal cycling.
In short: if you’re chasing power, reliability, or longevity, an uprated gasket isn’t just a luxury, it’s a necessity.
Standard Bore vs Oversized: What’s the Difference?
When selecting a head gasket, bore size matters. The bore refers to the diameter of the cylinder openings in the gasket, which must align with your engine’s cylinder bores.
- Standard Bore Gaskets: Match the factory bore size and are suitable for unmodified engines or those with minimal machining.
- Oversized Bore Gaskets: Feature slightly larger openings - typically 0.030" to 0.060" over the cylinder bore to accommodate engines that have been rebored or where combustion chamber geometry demands extra clearance.
Why Choose an Oversized Gasket?
- Prevent Overhang: Ensures the gasket doesn’t protrude into the combustion chamber, which could cause hot spots and detonation.
- Accommodate Machining: Useful when the block or head has been skimmed, altering the chamber shape or bore alignment.
- Compression Tuning: Slight changes in bore and thickness can be used to fine-tune compression ratios for performance builds.
Choosing the correct bore size is a balancing act, too tight risks interference, too loose sacrifices compression. Athena’s range offers precision options to suit both street and race applications.
