Agree on the 1 piece FelPro gasket. It comes with 4 plastic studs you use to hold gasket to block on the 4 corners. Then just slide pan over those studs, screw in side pan bolts them remove plastic ones and install the 4 corners. I use Permatex Black Ultra RTV. Better suited for high temp oil sealing vs other flavors

Must be something new 'cause a few years ago when I did mine ( 396, one-piece fel-pro ), I didn't get the plastic studs. I improvised by attaching the gasket to the pan with very small gauge wire, got a few bolts in to snug the pan to the block and removed the wire. In my case I had a hoist to raise the engine and place the 2x4 blocks under the mounts. No leaks from the pan since.
