That's a collection of mid 1980s Ford Racing parts.

Those are Ford/SVO heads, they came in 3 versions with catalog numbers M-6049-A3, M-6049-B351 and M-6049-C302. Can't tell which version from the picture, need to see the casting number below the valve cover, or we might possibly deduce which version by the dimensions of the intake port. The casting number is a little different than the catalog number, it will read something like E3ZM-6049-C3.

Those valve covers are Ford/SVO valve covers, M-6582-A351. They're magnesium, and they sell for big bucks on eBay. They were originally intended to act as a rocker stud stabilizer, similar to the function of a stud girdle. They're valuable today simply because people think they look "cool".

The intake manifold is a Ford/SVO manifold cast by Roush Engineering, either M-9424-A331 (351C only), M-9424-A351 (351W only) or M-9424-B351 (9.2 deck 351C OR 351W).

Does that block have a Motorsport/SVO number cast into it by any chance? M-6010-xxxx?

You won't know what the displacement is until you measure the bore & stroke.
