OK so I'm almost to the point of starting the wiring job on my '59 f100. It ain't got no wiring nowhere! I have a new harness with blade fuses, that's not a concern. What about all that space between the manifold and the valley pan? I'll be tucking wiring away wherever it's practicable. Yes I'm a bit anal about neat wiring jobs. I'll be putting my elec fan Tstat in the water pump and the alternator wiring is in the same ballpark.

Has anybody used this heat wrap or a close facsimile? Thoughts?

I like orderly wiringas well and don't like the look of wires crossing over to the enginefrom the fenders. On a 351C I ran all the coil, temperature, oilsender, alternator wiring between the valve cover and the intakemanifold with no additional protection and no apparent problems after8 years.

lr thanks. There may be a bit more heat under the intake, but not much. But this stuff isn't expensive. I also plan on having so many redundant grounds I'll probably add 2 pounds of weight.

You may want to block the exhaust cross over before you cook the wires. Especially if you run an Aluminum Intake.

I'll seond both Frank and Mark Most modern wiring systems use wire good to 300 degrees. Mine have been fine under the intake. On OT cars, I've used SS tube to run wires, standing off with Adel clamps. If the valley cover is 300 degrees, you've probably got worse problems. The loom you showed will be good mechanical protection, not so much for heat in that location.

I will be running a stock 2V manifold. If I go to 4V I'll search for a B code man

1500 degrees should be plenty. The factory stuff on my '88 Firebird is that black plastic convoluted sleeving, similar to what most parts stores sell. It has done it's job for 26 years and 160k miles.

You could make a standoff that mounts to the intake hold down studs or valve cover studs that will providea good spot for a couple zip ties and prevent direct contact with the hotter areas.
