Agree;
<div>mine is an original with the asbestos still on it in ok condition. That doesn’t concern me.
<div>My minor issue ( other than being lazy) is I have 3 spacers between the manifold and the carbs and no room on the studs for nuts to be put on if I install the shield unless I drop a spacer. <br>
I just need to do it as I have ample time these days unfortunately due to CV19 <br>

stainless piece the same shape as the old asbestos, attach it with bolts with a nut between the two for a spacer, for an improved version.<o:p></o:p></span></p>

<p class="MsoNormal">Just to continue the vapor lock talk, I don’t think my early BN7 had a heat shield on it as OEM. So several years ago after not driving much in the hot summers due to vapor lock issues, I bought a used but good heatshield from someone
on the list to put between the carbs and the intake manifold. <o:p></o:p></p>

that they act as an insulator between the heat source & the cooler fuel & fuel line. A cloths pin is about 1/2" wide. To have any measurable effect at all you would have to line the fuel line with cloths pins for several feet.
