Thanks for your reply. I've seen some pictures on the TTI headers and mounts in their stock locations and it seemed like it would create an interference with the modification you did. I'm guessing it was just angle of the photo.
There's so many holes not needed if you aren't using factory insulation or AC/heater box. I used an aftermarket wiring harness so I didn't even need the bulkhead hole. All of my headlight, horn, etc. wiring is run in the fender well.
Take a look at Deutsch connectors for your EFI harness. With these, you will have a weather tight connection instead of a big hole. I did a Holley Sniper EFI installation on a friends car and the hole has to be quite large to fit all the connectors through it.
You can barely seem mine in this photo. Once the air filter is on, it's hardly noticeable.

That is a nice clean look.
We decided to eliminate the cowl vents too, since the Classic Auto Air system does not use any outside air. It calls for closing off the passenger vent only but we eliminated both and smoothed the cowl area. Won't miss having the openings to collect needles, leaves water or anything else that typically gets collected in them.

Since the cowl vents are where the windshield washer nozzles normally are, we will install modern washer nozzles on the cowl. Will make use of the existing firewall nozzle holes to plumb the new nozzles.

Have a couple different styles. Will pick one based on spray pattern and best installation location.
I suppose they could go on the hood if we wanted but the cowl is the plan for now.

Both of these styles have nozzles that can be aimed.

I bought a pair that mount to the wiper blades too but already ruled those out.

I like that these use a nut to hold them in. I can reach up into the cowl from the inside through the opening under the dash to tighten them...

Here are a couple other views of the passenger side header.
