Edelbrock LS1/LS6 Valley Plates are designed for use with 1997-2004 GM LS1/LS6 engines and similar GM Gen III engines which have been converted from EFI to carbureted setups. The plates come packaged with a breather boss which needs to be drilled and tapped by those retaining the stock LS6 breather configuration, or for LS1 users looking to convert to an LS6 style.
