We are excited to announce the arrival of the Austin Healey 100 Aluminum Cylinder Heads after 3 years of R&D.

Fits all Austin Healey 100's (BN1 and BN2)

THESE GROUND BREAKING NEW CYLINDER HEADS ARE AVAILABLE NOW!

CYLINDER HEAD:

• Heat treaded LM25 aluminum for the alloy castings.
• This assembled Alloy Head weighs only 25.35 lbs, saving a massive 30.42 lbs over the original iron heads. 
• Assembled and tested by Master Engine builders. 
• Redesigned, ported combustion chambers return a slightly higher compression ratio for increased performance and efficiency.

CAD designed & CNC machined for accuracy and high quality finish.

• NEW & IMPROVED PORT DESIGN exhaustively tested over weeks of extensive flow and dyno testing.
• State of the art CNC machining and porting returned identical flow over the ports.
• Over 14 hours of meticulous machining with 4 of those on CNC porting alone.
  
• Significant BHP and Torque power gains when tested on our development engine using H4 carburettors and all standard engine components including the cast exhaust manifold. See the results for yourself on our dyno reading!
• Accuracy and consistency confirmed on every head before it ships.
• Every head is pressure tested.
• CNC cut seats provide a perfect valve seal.
• Modern stem seal design.
• Only the finest materials used

COMPETITION HEAD GASKET:

Classic Car Performance worked with Athena, one of the world’s leading gasket manufacturers to make a gasket specifically to perform with our new cylinder heads. They produce our high quality, multi layered all-steel head gaskets for the 100's Heads. The benefits:

• Provide an even torque load across the sealing surface to compensate any type of bore distortion.
• Outer and inner layers combination is designed to perform at higher compression levels than O.E Head Gaskets.
• Offer the best solution for both aluminium heads to cast iron blocks and aluminium heads to aluminium blocks.
• They are the same thickness as the OE gaskets so the compression is not affected.
• Highly effective for high compression competition engines BUT also standard road engines benefit greatly from the superior sealing qualities.
• Improved engine performance and longer durability.

Our new design MLS Head Gaskets are made from high grade 301 stainless steel full hard material. Each layer is individually formed using a state of the art laser cutting and embossed with an optimized formation process.

All head gasket layers go through a stress relieving process to significantly reduce embossment forming induced stress. Proprietary two part polymer coating is applied after the stress relieving process and ensures uniform coverage of the outer layers providing no break in the coating.

This process ensures the micro seal of engine coolant/oil fluids.
