Stock valve spring installed height

I wanted to find out if the stock spring installed height on the stock heads and vortecs should be the same, but is it 1.700 or 1.750?

I am building a set of vortecs for the Ty i just bought and the springs i have are designed for a 1.800 instaleld height and are good for up to .600 lift. I was thinking the stock setup is 1.750 and that way i can just get +.50 valve locks and be done with it, or even machine the valve seats down .050, im thinking there should be plenty of meat in the castings.

TIA
