My 520 was done by Competition Motorsports (ie Jerry) WITHOUT the deck plate. After it blew (who woulda thought) new engine builder was appalled about this.

He said that it is very little extra $$ but is usually done to save time. He rebored it with a plate, but now the clearances are a little more than I would like...still OK for a street motor but they would have been tighter had it been done right initially.
