my bet is you will never get the pan & 4 side gaskets [2 on each side ] in there & get the bolts started
had a friend rebuild engine with a stroker crank 12 years ago. He messed up the heads, so I had Chapman Racing Heads rebuild them.
Put engine together, but still worried about everything else, so had an guy one year later tear down the engine to make sure everything else
was ok. He said all he had to do different, besides put a crank scraper in, was double up the gaskets on each side of the valley pan, for both sides,
due to surfaces not mating correctly. I hope he got the bolts in well enough. Been working fine for 10 years. Maybe he used longer bolts from ARP?
