    • Introducing the HeadGames BMW S55 (F80 M3, F82 M4, F87 M2 Competition) valve spring kit - Ti retainers, single spring + Valves, Head Studs

      Remember a post from last year describing valve float issues high powered S55's run into? Remember HeadGames taking on the problem and finding a solution? Well, the parts they developed are now available to order with pricing and information below.


      New from HeadGames is the long awaited answer to your float whoah’s. Introducing the HeadGames S55 valve spring kit! This is the ONLY kit on the market that is truly designed to be used with a S55.

      The factory spring is weak, with only 50lb seat pressure and 150 open. Our spring boasts 90lbs closed and 190 open! (at 10mm lift)

      We worked with ASR/Kratos on testing these out, and the results speak for themselves. Will handle 1000whp with ease (working on a gen 2 that will handle more without affecting vanos)

      What’s included: Ti retainers, and single spring

      Direct drop in!

      THESE WILL NOT HELP IF YOU HAVE ALREADY BEEN VALVE FLOATING AND THE VALVES ARE NOT AT THE CORRECT HEIGHT ANYMORE. PLEASE MEASURE BEFORE YOU INSTALL

      Price $799+shipping

      VALVES:

      We are offering the only aftermarket valve available for the S55! Only come in standard size, these valves are made from a grade of inconel called Numonic 90 and are tested up to 2000whp in other applications. These are a direct replacement for your worn out stock valve! And not available anywhere else!

      Price $840 for 24 valves +shipping

      Head studs:

      When replacing your cylinder head to make it ready for boost, do you really want to reuse the factory head bolts? We worked with ASR/Kratos and found the perfect solution. ARP 2000 headstuds! Direct replacement and perfect fitment. THESE ARE IN LIMITED QUANTITY! (not rich so could only buy 10 sets)

      Price $995 +shipping
