[Tigers] Aluminum Heads--a downside?

[Drmoonstone at aol.com]

Essentially correct. Too everyone, for the last time I, AM NOT TALKING ABOUT 
THE DOWNSIDE OF ALUM HEADS BUT THE DETRIMENTAL EFFECTS OF PAINTING AND 
POLISHING ALUM HEADS. If you are running higher compression ratios you need Alum 
heads and any degradation to heat transfer effects the performance and durability 
of an alum headed engine! In some cases the increase in retained heat can 
cause failure due to heat retained and lose of Hp. 

We have a tell all in our Cermakrome line that causes the coated header to go 
dull and gray at sustained heat exceeding 1350 degrees F (melting point of 
the alum used in the cermaic/metallic coating). If it's dull and gray the engine 
is running super rich or very lean...all effecting performance of the 
product.
