[FWDLK] Exhaust Manifold Heat Riser

["Ron Waters" <Ronbo97@xxxxxxxx>]

There is a manifold heat riser on the right exhaust manifold of my 58
Plymouth.  Like most of these things, mine is frozen up.  A mechanic I
spoke to told me that they're not really necessary unless you plan to drive
your car in icy cold weather.  Since I only drive the Plymouth on warm
days, is this a good solution ?  What I actually did was open it up 2/3 of
the way, so a little heat will go up while most will go out the tailpipe.
Any thoughts on this ?
