Unless you really need the extra H.P. why spend the money. If you just want to spend money then spend it on something that at least can be seen. Buy a better intake, a better carb, a better distributor. If the right parts are used you will gain more H.P. from that than you will thermal coating.
You probably make more H.P. than you can hook up now...I know mine will when its done..but it sure will look pretty.
Just my thoughts.
