In a low compression N/A engine, it's not going to be an issue.

If it was a small chamber head, with a domed piston, I'd be wanting to remove any possible sharp edges and possible pre-ignition points. If it was an engine with several stages of nitrous, I'd be looking at enlarging the compressed area, to slow down the flame front.

A dished piston down the hole, with a factory chamber isn't going to encounter such issues.
