Try Comp 929-16, I have two sets that came off our Dart heads when we got them never used. I do not know who Dart uses for there valve springs but they are for Hyd Roller cam. $100.00 a set plus shipping. We could not use them RMbuilder wanted me to use Isky 8205plus the cam he did for us is .642 lift.

The Isky 8005 is a good spring for a 500.

Manley Nextech makes a good spring. I've been running them for 5 years on my 500 hp upgraded to 600's.
