The shield could easlily be taken for being white in the pic, BTW I´m also one of the circa 10% of all men being color blind.

The spark plug heat shields comes from the 1973 454 engine that is now in the truck, at least some of them. Can´t remember clearly since it was almost 10 years ago since I did the rebuild but I think there was some spark plug heat shields on the 402 as well. Will take a look at old rebuild pictures when I have access to the them, on a trip away from home right now.

Thought the spark plug heat shields would be a nice addition but it is probably not factory correct for a 71-72.
