I gave up on the one piece gaskets as well. They suck.

I never use the end pieces. I lay a bead of right stuff across both ends.

Use the 4 piece 1893 and throw away the end pieces. Use Ultra Black , for the ends . Just like an Intake Manifold , those end pieces will leak .

I used the 4 piece, on a pair of 580's, I used a light coat of permatex on the timing cover and rear main cap added front and rear seals and let it set over night, next day added the pan rail sides sealed all 4 corners and snugged it up and hope for the best.

Like said, I tried to use the one piece from a local store on a Mark IV one time and couldn't get the pan on. Had to have been a mistake so I ordered another on-line. Same issue. RTV and the four piece from that point on.
