No back to back tests. But I’ve made 620 with that Speedmaster intake. However the runners are short, which won’t help tq below peak.
Conversely the Torker has longer runners but not a good transition into them.
Edelbrock stopped making the Torker in 2018. There has to be a reason why.
If it’s a street application, where top end power is not the ultimate goal, I’d either use a regular Performer or an RPM.

I’ve made 540 with a multiport EFI’d Street Dominator. Good intake in my experience.
And I just did a 455 with ported Gen II Edelbrocks and a ported Port O Sonic that made 568 I believe. The build specs are on here.
But what is the application?

The super sonic is the single plane job with a Dominator flange. BIG BIG BIG. I haven't tried it yet but should I do so will be a TRW type 462 with a 28-29 camshaft. TU

May have been offered in 4150/60 flange and dominator, but I cannot recall anymore. Summit still sells them on special order basis.

Picture in SS ad is of a brand-x, disregard. Super Sonic actually less expensive then the Port-O-Sonic. Looks like some lead time when ordering.

Those have proven to be a very good intake. I’ll be doing another Stroker BB build with one very soon. Multiport EFI, cleaned up Gen III Edelbrocks and a decent cam etc. Should be a fun one.

Are the runner cross sections on the super sonic bigger than the port o sonic? It don’t look like it.
