I used a tiny bit of sealant just on the corners of the half circles in the gasket because when I placed the gasket on it didn't contact on these parts and lifted slightly.
Put some tiny blobs of sealant on and then used big washers on the corner bolts to push the gasket flat where its supposed to go and bolted the gasket to the sump.
Then after 24 hours offered the sump with glued gasket up to the block.
