I'll bet it makes very little difference in the grand scheme of things if
painted or polished, the cooling system takes the brunt of the BTU's out of
the motor not the radiation from the surface of the heads.

Sorry for the late comment. With aluminum heads, polishing and painting really
negates much of the performance valve of the material. For higher compression
aluminum heads should not be painted or polished.

Hi Dave,
Jeez---At least
replace those tired old heads. There are some
aftermarket iron ones around,
or you can paint the aluminum ones. Aluminum
heads give power & actually can
run w/out knocking on 87 octane. They'll
run cooler, too---a bonus for a
Tiger.
I run a "baby crower" cam in my Mustang to retain the idle quality
&
give great torque. But to improve the HPower you need attend to the big
3---Heads, Cam, and Intake (or a power adder).
Why in the world would you
want to spend all that $$$ and still have a
car that can't even keep up with
a Toyota?
