Stock 5.0 valve springs

why would you want stock one anyways - i bought a set of doubles one time for like 90 bucks new - good up to .600 lift - i asume you just want to put atock spec ones back in to save the cash? - or because you're using all other stock valve train to include the cam?
 
this is the plan. ive got a spare set of heads. and ive never done porting before. ive got a rotary tool. and ive got alot of time and theres plenty of reference out there. ive already got a car that runs. so if all goes well then maybe ill save some cash and use the heads that i ported. im just piecing things together to see where im at. but, yeah i am using all other stock valve train parts at this point. if i get more money maybe ill use it.
