Sam,
You may not want to clutter the engine with water lines. But I truly believe/ know that heating , will make it vaporize the fuel that lays in the intake better. Makes for a more responsive engine.
Looking at your intake pics. That Clifford does not look to have heating provisions.
Hank, Don't knock it till you try it. I am not telling him to spend 300-500 on un needed parts.
I also think the 6.5 PV is best to use. On the highway 12 inches of vacuum will be all you see. any hill and you will be into a 8.5 PV when you don't need to be.
