Included is two pan rail gaskets that have a steel shim inside for durability and won't split or tear. Gasket is 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 Donovan 700 BBC leak free.
Gaskets are .080" thick with Teflon coating on one side, stud holes are .360" and are set up for Donovan 700 racing blocks only, not to be used with passenger car type engine blocks. Gasket is to be used with two piece rear main seal.
