Re: [FWDLK] intake manifold restoration

WOW!  A factory installed valley pan!  I'm no expert but all I've ever seen
is fiberglass insulation stuffed under the intake to keep it cool.
Maybe someone in the past 47 years removed the intake and reinstalled it
with a valley pan.
I think they're a worthwhile investment, like windage trays if you're there.
There's also some chatter about making heat shields for fuel pumps.
