Missed on this combo?

I had a set of Hughes cnc ported SB RPM’s here for freshening a few years ago.
From what I gathered, they were the biggest version, without going to the BM(no offset rocker required).

I was shocked at how flat the floor and SSR were.
Equally surprised that you could take the floor that low without ending up with a hole.
They had 2.08 intake valves, and the chamber was blown out pretty good.

Without digging through my notes, I wanna say the “big number” was in the 280 range.

They sounded very rough on the bench at high lifts as well, but I don’t remember the numbers backing up.

Edit: looked it up

I’d like to get a BM version on my bench.
