COMP Cams offers a simple but effective solution to this problem - a thin, hardened steel alloy seat which will not only protect the head and shim but also locate and hold the spring in place. Previously, this part has been available only in a cup form with the retaining portion being on the outside of the part. This required that the head be machined a great deal to accept this cup so COMP now offers an I.D. locator with the locating shoulder on the inside, as well as the spring cup. Many sizes are available to locate from the inside or outside diameter.\u003ch5\u003eResources\u003c\/h5\u003e\u003cstrong\u003e\u003ca href=\"http:\/\/digital-assets.partshub.com\/BDQQ\/dddbebdc29809.pdf\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eSee 4779-1 for a single seat spacer.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eEngine Valve Spring Seat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003eSeat Spacer Set 100 for BBC - 1.568\" OD, .623\" ID, .300\" Thick\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_INV\u003c\/td\u003e\n\u003ctd\u003eSeats BBC 1.568\" OD .623\" ID .300\" Thick\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003eCup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003eLocator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003eSeat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003eSpring Cup\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_KEY\u003c\/td\u003e\n\u003ctd\u003eSpring Seat\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_MKT\u003c\/td\u003e\n\u003ctd\u003eThe older style standard shims will not hold up to the extreme spring pressures and high RPM found in racing engines being built today.
