Probably already checked but most of the aftermarket oil pan bolts are a touch longer than factory and will bottom out and not compress the gasket. Found this out my hemi. I thought it was rear main also. My easy solution was to add 1 grade 8 flat washer to each bolt.
My block has studs for the oil pan, so my pans tightened right up against the block. Thanks for the heads up though.
