Valve Spring Retainer ??

lhearold said
What I have had to do is get valves with longer stems and then shim to get back to where needed. If its only a few thousandths off you may be able to go thru hughs or comp cams and se if they have retainers that will raise the spring height up. Seems like comp cams had several different ones. Shame Crane Cams is no long er around. They had a full line of them for MOPAR.

Longer valves should be researched because the longer length can put the rocker contact patch in a less desirable location.

You'll need to do some research to see which parts they have that will match up with your existing parts while increasing the installed height.
