Does anyone have a clue what the R-Value is on the Styrofoam forms used these days for basements?

1/2" is 3.3, 5/8 is 4.1, 3/4 is 5 and 1" is 6.5 r value

It is simply a measurement of thermal resistance. Something to slow the transfer of heat through a building assembly. All materials, believe it or not, have some R-value.
For example, Drywall has an R-value of about R0.3, Vapour barrier R0.07, Pink Batt insulation in a 2x4 wall is R12, and exterior sheathing or plywood is R0.4.
The whole assembly acts as your R-value and not just the insulation in the wall, even though it is the greatest contributor.

The R value is a number that manufacturer's assign to their products stating their insulation, or Resistance to heat value. The higher the R value, the higher the products ability to stop heat transfer. I am assuming you are asking its definition, and not the actual value for the Styrofoam forms. This number should be printed on the product.

Trojan thintensity is a high quality product for that. Make sure you're not using any oil based products with it, though, as that will reduce it's r-value, and may cause leaks.

different Styrofoam has different values if you look at the styro it should be listed on it. if not you take a chance. go to Home Depot or Lowe's and see what each styro is rated for..
