What valve springs for F303 Cam?

I'm getting ready to install a FRPP F303 camshaft with new lifters and pushrods after I get my new intake and was wondering what valve springs i should get. For the moment i'm going to be using a set of stock heads that i'm going to have ported at my local machine shop, but would like to install better springs for this lopey cam. The lift for this cam is 0.512" for the intake and the exhaust. Trick Flow has a kit TFS-2500100 and so does Crane Cams CRN-44308-1. I was wondering if anyone has used either of these before. Thanks for the input.

Thanks Thumper, I didn't know about the Ford Racing springs. Do you have a preference on which brand of springs. I've had problems with Trick Flow before, but it was on my friends '95 intake. Just wondered what most prefer. Thanks again.
