Theolder style standard shimswill not hold up to theextreme spring pressures andhigh RPM found in racingengines being built today.COMP Cams offers a simple buteffective solution to this problem - a thin,hardened steel alloy seatwhich will not only protectthe head and shim butalso locate and hold thespring in place. Previously,this part has been availableonly in a cup form withthe retaining portion beingon the outside of the part.This required that the head be machined a greatdeal to accept this cup soCOMP now offers an I.D.locator with the locating shoulder on theinside, as well as the springcup. Many sizes are availableto locate from theinside or outside diameter.
