Small Block Chevy Aluminum 205cc Performance Heads

Product Description

  • All engines are not created equally.  This combination is not your average run-of-the-mill bolt together package like you may find elsewhere for less money.  Gregg Hekimian, MIT Thermal Physicist and Mechanical Engineer, personally designs and assembles each engine to exact specifications, getting it right the first time.Hekimian Racing Engines does not substitute quality, reliability or power for cost.  Each engine undergoes rigorous quality control checks.  You get what you pay for.  Our engines are  built to last and to handle brute forces.
