Are the valve covers on D15b's alluminum or steel? i was told if theyt are alluminum then they wont ground out? and i see people putting their ground wires on the valve cover all the time, so thats what i decided to do? but is it going to make a difference if the head isnt steel? anyway basically what i am asking is it steel or allumiunum

 

alum..

get a magnet.. if it sticks ...ferous.. or usually steel..

if it doesn't stick.. alum.

so basically there is no point and grounding it on the valve cover?

 

nope you can still ground to it

 

Aluminum conducts electricity, so yes, it can be grounded.
