The "Fuelie" heads can be used on pretty much any SBC. They got the name "Fuelie heads" because they were used on the early Fuel injected SBCs.
They were also used on a lot of other "high performance" applications including 327s, 302s, etc.
If you're looking to get into the 11s, or 12s, there are much better options in the aftermarket.
I'm not saying they aren't decent heads, but with todays tchnology, there are MUCH better heads available.
FWIW, I'm running the 461s on a fairly radical 355, and it does run well. I've never had it to the strip, but it's one hell of a street machine.
In my 69 Nova, I would expect at least high 12s...maybe a little better, but no time slips to back that up yet.
If you can pick them up $50.00, unless they're junk, I'd grab them.
And...the 327 is surely worth $100.00 if it's in re-buildable condition.
That would make a nice high winding street motor in your 64.
