On my first gen I have to remove the OFA to have enough clearance to pull the engine, is there enough clearance on a second gen or should I leave it off the new engine until installed? Will my L67 flywheel bolt to torque converter the L36 is currently bolted to? I'm going to leave the stock 4T65 in there for now.

You'll either need to slot the holes on l67 plate or run l67 converter. There is room to pull with ofa but is still worth pulling off first.

Did different cars get different stall converters? Like H body vs W body or whatever the Riv is?

Nope. All with same engine option should have same converter. Say if donor was a 98 riv just use the converter from that

One advantage I found on topswap is l36/26 flexplates are drilled for both converters :)

The Rivi is a FWD G body. It's the same platform as the Aurora.

Yeah, the L67 flywheel is balanced to an L67. I wasn't sure the 4T65 had the same input shaft spline as an HD. I'm going to buy a whole HD fw $200 from a running car this week so that'll give me a converter. This would be a fun place to post a pic of my "3800 Only!" modified engine stand, lol.

Yeah internally 4t65s are the same. In fact over on gpf l36 converter swap was a popular fad lol

Was the stall better on the L36 converter or something?

All the ones I've seen were dual drilled. As far back as 97

They're definitely not all drilled.  The L36 I put in my '98 Regal did not have a dual drilled flex plate.

I've seen them both multi drilled and single drilled. Best advise I have is to verify on a per application basis.
