Does this car look squatted

About equivalent to stock.

The boat could be shocks. Could be shocks and springs.
Body roll could be the above or it could be normal. Depends on how much time you've spent in cars and trucks from the 60s and 70s.

Really nothing gained by throwing parts at it. Half the stuff sold these days is junk.
Get a shop manual. A factory one - not a generic.
Get a set of jack stands, wheel chocks, and jack; and some cardboard to lay on.
Measure the ride height. Check the condition of everything on the suspension and steering.
Also check the wheel bearings, joints - and make sure you follow the shop manual on checking the upper and lower ball joints!
Then make your shopping list.

If you want a little better street handling and its not equiped with the optional anti-sway bar, get one.

To give you a bit more perspective to where your stance is, here's a pic of my 71'. It sits perfectly level, has 17" wheels and the tire height is 25". Top of front tire even with the wheel arch and rear wheel tucked up inside.

Yours looks a tad bit lower on the rear, which mentioned in prior posts is probably due to age. You can either re-arc the leaf springs, buy new ones or add an ugly shackle.

I'm curious, does the car have the bachelor lean? Left side lower than the right side, due to solo occupancy over the years.

I have TTI headers and they hang evenly with the transmission oil pan on mine. I don't understand why one header would be lower than the other, unless they're mismatched or a cheaper set.
