I know this doesn’t answer your question directly but this might be something to think about: since you mentioned you like the idea of a little neck snapping performance, I wouldn’t mess with that 402. Go to the junkyard and pick up a 454 roller motor. I noticed them in junkyards here in Colorado all the time and they usually go to the crusher because everybody wants an LS these days. I speak from experience when I say I would never rebuild a 396 or 402 for anything other than a restoration. If performance is what you’re after it’s more than worth it to step up to a 454. It’s actually a bit cheaper to build a flat tappet 454 than a 402 and the torque increase and fun factor goes way up. A 454 has so much torque you don’t even need to mess with aftermarket torque converters, your stock one will work just fine. What I don’t have experience with is a 454 roller motor rebuild and swap. Do an evening worth of reading and I’m sure you can find out the little details that will make the swap a slightly different from the typical old style 402/454. A slightly more difficult find but still very doable is to pick up a flat tappet 454 core and use your 268H in that. That cam would work great in an otherwise stock 454 with some compression. Just my two cents ......
