I don't have time right this moment to go find the first huge Olds Rocket thread on here started by "Rocket Daemon", That will tell. I know the old racer that I got a lot of stuff from, ran 57-58 371 heads on his 324 back in the late 50s early 60s. .
the first big areas that will cause issue will be valves hitting cylinder walls, and push rod angles (lifter spacing) and push rods guide hole alignment.
