Short deck deck intake?

I wonder if it refers to how low the intake sits on the front and rear raised sections of the block?
Some call the rear section the "China Wall".
Today I installed an intake on my 360 and helped Rich with his 5.9/408. Both intakes were the Edelbrock RPM Air Gap. Mine needed the cork gaskets on the front and rear wall to get the holes in the heads to line up with the intake.
With his engine, the cork gaskets put the intake too high and threading the intake bolts into the heads looked like it could be difficult and maybe even damage the threads in the heads. We had to pull the cork gaskets and put a thick bead of RTV on the front and rear wall. If there is a thinner gasket for that, it would be a cleaner option.

When I first read the thread title I thought B vs RB but then before opening the thread I noticed it was in the small block forum.... No short deck that I'm aware of....
We run 9.20 Short Deck R Blocks in out Superstock A engines.
We machine down a production deck height manifold often which is a
time consuming pain in the butt.

On some Mopar race blocks, the distance from the centerline of the crankshaft to the cylinder head deck surface is 9.6 inches and the "short deck" is 9.2 inches. Hope that's clear.
I thought that to be Super Stock legal the block has to be OE deck height?
Did NHRA change the rule on that?

First picture is a 428 short deck aluminum W2 Batten heads. The second is a tall deck with 416 with a standard intake. Look at the flange thickness . totally different .

that's like looking at 302 and a 351w fords. the intake is much narrower on the short deck motor.
