There was a thread on here a while back about this same issue. The Edelbrock Performer is considered the closest to stock of the aftermarket manifolds available...and it is something like 3/4" taller than stock.
The old Mopar M1 dual plane was just an aluminum copy of the '69-'70 HP manifold. No power increase, but saves a bunch of weight.

The Edelbrock DP4B (383) and CH4B (440) are the next step up from the Performer. Again, slightly taller than stock, but also slightly larger runners for a little more power.

I think the Holley SD will be way too tall to use w/o some serious modifications to the air cleaner. If you can get it to work, that's great b/c it is an awesome manifold. It is old, but it works GREAT.
The Holley SD and the Edelbrock Performer RPM both work great, but the RPM is even taller than the SD.
