As the title states, I am trying to find information on using the Mopar performance springs (5249464) with the later triple groove valves.
A little background, I have a 2000 Cherokee with a rebuilt 4.0, .030 over with a Comp Cam 68-232-4, 630 head with some mild port work running stock valves and magnum springs. I have been chasing a valve train noise for some time and after looking at the spring specs, I am realizing that there a good chance that the lift with this cam is causing coil bind.
All this had lead me to searching for better spring options. After a lot of searching the easiest answer that doesn't require machining is the MP springs. They state that you are supposed to use the recommended retainers (P4452032) and keepers with these springs. Which are a single groove 8*.
The question I a trying to find an answer to is, is there a way to use these retainers without swapping to earlier valves?
I have read in some threads people referencing that the three groove keepers are 8*. And some stating the the hemi 5.7 and 6.1 keepers are three groove 8*, but have been unable to confirm this anywhere. So I was hoping someone could help me
