Help identify these heads

Would these heads be a bad choice for a 360 or 408 in a 86 Ram 4x4? I’d like it to be pretty tame and run 87 octane if possible. I want the truck to be a daily driver.

Theyll be fine if you can get the compression low enough. Maybe a dish piston with a step for quench. Run on 87? Maybe 9:1-ish with a wide lsa cam.
