For out of the Box bolt on, I'd say the Trick Flow heads as they are CNC ported (flow as advertised out of the box) and come with a selection of springs / retainers that you can select to usually match your cam.
Just about all will need the reduce wrenching head bolt kit.
I don't know about using stock rocker arms on the Trick flow heads? I used the recommended Harlan Sharpe roller rockers, but the price of them are really expensive now days.
I have never used an Edelbrock E-street, and not sure how they differ from the RPM heads. The RPM heads are pretty common as a "bolt-on" head, but like most of these, it is best to have then checked out before using them. Most of these as-cast non-CNC heads usually flow less than advertised and need port cleanup and valve job to get them to flow as advertised.
I think there are some off-shore knock-offs of the Edelbrock Heads (streetmaster, procomp?), but again, never had any of those.
I do have 440 source stealth heads on the 505" stroker, but I tore them apart, and did some bowl and port cleanup, multi-angle valve job and replaced the springs and retainers, so not really a bolt on for my use, but they do look closer to factory than the other aluminum heads.
I recently got a set of the CNC ported 440 source stealth heads still in the box. I will check them out. I am hoping all i have to do is replace the springs and retainers for the cam I use.
