Rear/Cam Expansion Plug- Which way out?

[Wolverine]

First, because the FREEZE PLUG kit I bought for my 351C build had a 2 5/32 plug in it for the rear cam/expansion plug, and the size of the hole in my block is 2 1/4, I am assuming there are two different sizes of expansion plugs for this application.

This question is for the 2 1/4 application.

Which way does the expansion plug go in?

Does the LIP side go in first(unlike all the other freeze plugs) and get pressed/hammered in until it seats?

Or, does it go in as all the other freeze plugs, until it is flush with the block surface?

Thank you for your support, as always.

It goes in like the other plugs. Freeze it first to shrink it. It's half as deep as the other plugs so don't drive it in too far, just clear the edge.
