paint on the inside of heads flaking

I know this doesn't help but out of curiosity, was the paint sprayed on or brushed on?

I never had a problem like that using a brush. And what kind of paint was used?
im pretty sure it was sprayed but im not 100% sure

Maybe it's just a little overspray. Are you sure it's all the way into the heads? Like under the Rockers etc.?? Might not be too bad. GL
under the rockers is painted , even the springs were painted
