This is our own BimmerHeads exclusive “Ultimate” head gasket set! Unhappy with sets offered by other companies we have assembled our own. What makes this set stand out from the rest is the fact that it includes a Goetze head gasket, a Goetze throttle body gasket, and an intake vacuum plate gasket. No other M20 head gasket set includes these items. This set includes everything you need and nothing you don’t!
