Where to buy new 302 stock valve springs

[roadrunner19va]

Where can I buy new valve springs for my stock 302. I beleive it has e7 heads. Anyone know of a good cheap place and around how much. When i go WOT I hear a fluttering sound. I believe it is the valves floating. I am about to replace my intake so I fiqure I would replace the springs to. Thanks Travis

Have a machine shop check them first. I'd question your lifters before I'd question the springs; although neither typically fail without high mileage or lots of abuse.

Valve springs

The car only has 51000 original miles on it. The car sat in a garage for 9 years. The car runs great it just has that fluttering noise on WOT. What else could I check. How do I tell if the valve springs or rocker arms are bad?

I seriously doubt either the valve springs or rocker arms are bad. If the car sat for a long length of time, you may have a couple gummed up lifters. There are additives you can put in your oil, run the car, then drain the oil right away to take care of this.
