I recall regular enamel paint is good for about 300 degrees. That's what I was going to use as a top coat.
I really don't want to strip off the primer so I may find out directly when the car gets running again. Thanks guys !
Not sure, exhaust runs through the later intakes. They get hot enough to burn virtually any paint off. That's the beauty of aluminum intakes. They dissipate heat so much faster than cast iron that paint stays put. Does exhaust heat the straight eight intake?
