I can't help you on the valve springs, but you can buy pedistal mount roller rockers from any of the popular rocker companies. If you want adustable rockers, you'll have to have the heads machined to accept studs or, Crane offers a kit that allows stud mounted adjustable rockers on pedistal style heads, that requires no maching. I have these on my 351W with GT40Ps, and they work great (this is in a F150 4X4 that gets the crap run out of it by my 19 year old Son), though I wouldn't use them on a serious high RPM race motor (they retain the small 5/16" thread into the head)
