Default Powder coating or ceramic coat block

So besides easy clean up is there a point for powder coating a block and heads?

I mean it looks nice out of the engine bay but once inside you can't really see the block anyway...

Does it help with bay temps at all? I'd think ceramic would be better for temps... But I'm sure prices would be higher and I'm not sure of its even worth it.

Any experience or logical opinions?

I'm about ready to build my block and had this in my mind

Tnx

No there's no point. You'll only increase heat retention inside the engine and it'll come off in spots over time anyway.

As said above, there's really no point to it. Back in the day of cast iron engine blocks they were painted as a means to deter corrosion, and heat dissipation was a non-issue. With modern aluminum blocks corrosion is much less an issue and the aluminum does dissipate heat significantly faster. Any coating will reduce the ability to dissipate that heat.
