Vic,
did you CC that intake runner?
they dont give you much to play with at all with the LA heads.
i did a VERY minor clean up on a 596 head, still used a tulip 1.88 valve.......barely flowed like 230cfm(flowed 195-ish OOTB with OE valve and OE VJ).....and it was 165cc's.......or, 5 cc's too big to be legal in SS.
what are some of the other magnum head casting numbers?
i didnt see a "466" on the approved NHRA list.
68 Satellite, 383 with stock 906’s, 3550lbs, 11.18@123

I did not cc the runner on this Magnum head. Only trying to see what all the fuss was on the these things and didn't want to give an unfounded opinion. So, I ate iron dust for an afternoon to see. I thought it was decent information to share.  I'll try you at the shop tomorrow.

Have you looked at the old Ryan J ported magnums in the archives section? Looks like he did more work in the bowls and less in the PR pinch and got a little more flow that way. He got a hair more out of a stock set so that has to be considered but still he got around 270 might be worth a try.

I only did this to satisfy what little curiousity I had about the Magnum
heads and now feel as I've educated myself well enough to stick with
what I'm used to.
Despite the lack of "shine", I was pretty thorough and don't see this port
getting much better. An R/T head might be a different story but, as a
Super Stock head, I see a few disadvantages if these were legal.

My neighbor Joe E. was running a '68 Dart in IHRA Crate Motor until the class went away. He converted it to an NHRA GT car with the '89 360 308 heads combo. The HP factor is pretty low from what I remember. Ran some 10.20's without much testing. It's still running 9" tires too.
Top Stock went away, not the regular IHRA Crate Motor classes.
Several people are putting a Challenger Drag Pak 360 Magnum into older cars for SS/GT. There were only 3 Challengers ordered with that engine in the first year of Drag Paks.But al it takes is one to make it legal. Soft HP factor so far.
