The BimmerHeads Race M20 cylinder heads are for those who are truly power hungry. This version of our 885 head is great for those planning to build high horsepower stroker M20 engines or turbo monsters. This is what we would consider to be a “Stage 3” cylinder head. This head comes standard with new OEM BMW dual valve springs and Supertech stainless steel black nitride valves with the options to upgrade to our performance dual springs and +1mm oversized Supertech valves. The Supertech +1mm valves use a stainless steel black nitride intake valve and an inconel exhaust valve. Our Race head also allows the option of coolant jacket welding for high boost applications. Our Race cylinder heads are completely torn down and rebuilt receiving the following:

  • Cleaning
  • Pressure testing
  • Resurfacing
  • Valve grinding & valve seat grinding
  • New valve guides
  • New valve seals & cam seals
  • New intake studs & exhaust studs
  • New rocker arm hardware & eccentrics
  • Refurbished and coated camshaft gear
  • New cam gear dust cover
  • New Heavy Duty rocker arms
  • Extensive porting & polishing by hand (including combustion chamber)

Our cylinder heads are built to order. There are no cancellations allowed on cylinder head orders. Please expect a minimum lead time of 8 weeks due to our current workload.

Price INCLUDES a refundable $500 core charge. Once you have received your BimmerHeads cylinder head please re-use our packaging to send your core 885 cylinder head back to us. Once your core has passed our inspection and testing you will be issued a refund.
