  • Cast Aluminum is produced through a casting process, where molten aluminum is poured into molds, making it ideal for parts with complex shapes and varying thicknesses. This method provides good strength and corrosion resistance.
  • Billet Aluminum, on the other hand, is crafted from a solid block of aluminum through forging and machining. This process results in higher strength and durability, making it suitable for high-precision and demanding applications.

FAQs

Q1: SPELAB Aftermarket What are the differences between Hemi valve covers and OEM valve covers?
A1:

• Material difference: SPELAB valve covers are made of high quality aluminum, whereas OEM valve covers are usually made of plastic.
• Design and size: SPELAB valve covers are more rectangular in shape and higher in height to provide more interior space, while OEM's are more cylindrical in shape.

Q2: Why are SPELAB aftermarket Hemi valve covers designed with a larger internal space?
A2: The larger internal space in the SPELAB valve cover serves several purposes:

• Improved airflow and cooling: The larger space allows for smoother airflow inside the valve chamber, resulting in faster cooling.
  
• Reduced oil vapor build-up: The larger interior space allows oil to flow more evenly back into the sump, preventing oil vapor build-up.
