Also, has car been driven in warm weather and run long enough to fully warm the engine? A distant possibility is the racing manifold with no heat crossover.

Yes..i know about the heat risers using a Navarro racing...i learn that i need to run the engine about 10 minutes to warm it,,when i rebuild the old 97 i try the brass float with fuel inside...i was happy thinking that probably the problem was solved..so i put the new dual Navarro intake ..learn about warm the engine etc etc...but ...that fastidious problem come back after run the new plugs for a short trip....another thing that i have is the fuse of electric fan that jumps frequently...
