How bad are stock valveprings for D8OE heads ?

With my new cam, I was wondering if I could use the stock D80E springs or if I needed to get slightly stiffer ones. The lift is only about .040 higher on the intake and .012 higher on the exhaust, so I figured it would be ok. If I did actually need new springs, what are some you guys recommend? Ny stock ones were about 1.695 in tall (installed) had an O.D. of 1.430, and had an I.D. of about 1.030. I really don't want to machine down the spring pocket, especially because I'll be pouring money into crap D80E heads, or slightly better but still cheap E7 heads. (I know, I know, GT40 is the way to go, I'm just on a tight budget right now.) It's a lot to get, but if you guys could help a brother out it would be great!

D8 heads?
I wouldn't bother with them.
Sorry, but those are among the worst SBF heads ever made.
They make the E7s look good.
I know that is probably not what you were looking to hear, but...
