Can't find it, but as I recall someone listed on here that he used valvesprings and retainers from a Trans Sporter on a 4.0 head,what year and engine did they come from,would like to try them out on my new ported head when it's done,so tired of bouncing valves as it is now.
Thnx/ Hasse.

Don`t have an specific answer but why not Engle 593`s ? You don`t mention what cam your running but the 593`s work well for lifts under .500 ish.

My camshaft is a Crane with .484/.512 lift,and if I remember correctly those V6 springs should work up to .525
