JE dome pistons for BBM will fit in the Indy heads, and possibly the TF heads.
Will not fit the others you listed.
Forget the B1 heads for what you’re doing.
SRcnc295’s or the TF 270’s will make the power you’re looking for, assuming the rest of the combo is correct.
Indy EZ295’s would also be fine.
You said you’re building a 493……so the “440” is incorrect.
The real world numbers…….from over 20 years ago…….
14:1 493, std port SR’s flowing 320-ish, TG4500 intake, .660 roller cam.
630tq@4700/692hp@6800
2.16hp/cfm
A few years later, opened heads to MW size for a modest increase in flow(upper 330’s), paired with Indy 440-3 manifold.
Installed top end and cam on 14:1 557” short block.
770hp.
2.26hp/cfm
