5.9 mag spring question

[dudeman601]

Is there a spring/retainer for the magnum head that can be used for a cam with lets say 520 or so lift that does not require machine work to the head?

Hughes sells a spring /retainer kit that will go .550 lift.Installed,with a handheld spring compreeor on a engine stand.You are limited to.520ish lift with stock valve guides.

Nice grind.FWIW,Stock magnum heads peak .480-.490 lift.I like the aggressive split.Good cam grind,good luck!
