Finally get to pretend I am one of the cool kids - Holley kit swap

So my wife opened the garage door to get her car out and I couldn't help but step out and poke around some.

Here are some pictures of the mount and how the washer helps keep the motor locate.

I also tried to twist the motor and it feels very solid. So I don't think there is a twist that is causing the offset that I am measuring.

I also snapped some more pictures of the header to inner fender clearance and the clearance to the valve cover on the PS.

In addition, I grabbed some allen wrenches and used them to check clearances. Looks like the tightest spot on the header is about 7/64" clear and on the PS there is about 1/4" clear between the VC and the inner fender.

After looking at it some more, I am starting to wonder if Holley didn't intentionally slide the motor over 1/8" to gain some clearance for the VC. I've heard that can be a trouble spot and my brother on his '71 Demon build using Holley's billet VC had to notch his inner fender. So maybe I am good and am starting to lean towards not doing anything.

@racerjoe, how much clearance do you have on your PS valve cover? Ever tried to remove it with the motor in the car? @Dantra, too late to ask how close your VC was, but maybe you have an idea how my motor location compares to yours with the above pictures? @Map63Vette, any comparison info?
