What do you guys think of the speedmaster bare aluminum heads

I love hearing about what all these various heads “need”....... without anyone asking what they’re going on or how they’ll be used.

Imo, the only thing that “should” be done for pretty much any application is to make sure there are no issues that could cause an actual “problem” when put into service.
Aside from that...... the rest is all personal preferences......... based on the intended use, application, and desired power level.
