Included is two pan rail gaskets that are trimmed out for connecting rod clearance with bolt/stud holes at a main cap location on the block. Gaskets have a steel shim inside for durability and won't split or tear and are made from SCE's Accu- Seal material that won't absorb oil like the cheap white gaskets. Last on the list are two nitrile end seals to make a complete kit that will keep the bottom of your Stroked BBC leak free.
Gaskets are .080" thick with Teflon coating on one side, compare to Fel-Pro #1893. Stud holes are .390" and are set up for racing blocks only, not to be used with passenger car type engine blocks. Gasket is to be used with two piece rear main seal.
