Does GM or Felpro make a gasket kit which requires everything you will need when you replace the OPTI? I have just purchased and MSD OPTI if this helps. Anyone know the part number for the kit?

Thanks!

It all depends on what you want to replace. I've done the opti install and replaced nothing. OTOH, I've also done the swap and replaced the opti seal, water pump shaft seal, crank hub seal, and water pump gaskets. You can get all of those gaskets (plus some) in a Felpro set (timing chain cover gasket set) from Autozone (possibly in stock) for like $8.

The only things you must replace are the water pump gaskets.
