Correct, but not made anymore? That’s what I thought.

That's correct, the good EQ casting was cast in New Zealand and they aren't made anymore. You would have to luck into a used or NOS set at this point.
Same with the RHS Indy-X heads.

And they were very good heads. Such a shame there not made anymore.
Speedmaster any Good ?
Just type "Speedmaster" in the search box. Lots of threads about them. Like most alloy heads, send them off to the machine shop for more work. (depending on what you are building) A few guys pull them out of the box and bolt them on but I wouldn't recommend it.
Not to great as cast. IIRC, @MOPAROFFICIAL did a thread on them. Worth while looking up and reading.
In fact I stickied a index thread in the small block forum with most of the Speedmaster threads listed.
Indy has a Magnum style X head that flows 250 CFM @ .450

Something used that’s already been reworked....... or some new import heads that someone does the port work on themselves(or has a friend who works really cheap).

Happy bench compliments of Shady dellll 212 @.400 is a little high imo. But hey..better vj or the cherry port of the 4.
Don’t you have some head flow numbers from the Magnum head stock and ported?

One of the things I was happy to read in that thread was him saying not to compare flow numbers from different benches. That’s what they did on his bench on that day. And the only numbers that are comparable are numbers from heads that have been on his bench. Which he does list.

After some work they're good head.
Either with magnum valves, chamber work and a mill to bring then down to 61cc..or add guide work for 11/32 or 5/16 and up the size to 2.02
