More Stroker Pictures and some questions?

You can glue two together and I have done that before. It looks kinda funky though and when I did mine they leaked at the rail using the same valve covers you have. Put a straight edge on the rails of those covers and make sure their not twisted. Mine were fine and did not leak until about 5 minutes into break in on the Dyno then they started spewing oil like crazy all over the motor, headers etc. we aborted the run , cleaned it up and luckily the Dyno operator had a different set od covers so we swapped them out. Scary cause we were breaking in the cam a BIG "solid flat Tappet" we were worried the cam may go flat cause of the short aborted run but luckily all was fine.
I could not imagine cleaning up a big *** mess like that with the engine installed in the car while breaking in the cam on a new motor. It must have pumped 2-3 quarts of oil out. Was an easy clean up on the Dyno.
