Here's the low profile fitting.

Front view of sender problem. Thanks site.

Thanks for site on low profile elbow. Sorry about typing err.

First, is the manifold square bore or spread bore? Regardless, I'd run a spacer under the carb to gain access to the vacuum fitting.
The pcv should connect to the fitting out of the back of the carb along with a fitting from the breather to the air cleaner.
To use the angle of water gooseneck that you have you'll have to drill and tap the boss in the manifold on the other side or relocate to the head.

Can you move the sender to the other side of the manifold? If not, you could put it in the head where the stock senders were. I like them in the manifold better though.

Looks like there is a cast in boss just to the left of the thermostat housing. I'll have to check the Edelbrock manifold I have in the shop, but you may be able to drill and tap that boss for a sender.

I'm not that up on Holley carbs, so I'll leave the PCV questions to those that are. I would try hard to retain the PCV though.

I'll get back to you later.

This is the boss I was talking about. Your manifold appears to be identical to this one except that this hole is not drilled. You can easily reach under that boss through the thermostat hole to see if the area is open to the water passage. If it is, it should be simple to drill and tap it for your sender.
