0331 valve spring help

[jeepota]

Im using the 0331 head off my 2001 cherokee on my stroker and ive read these have the conical springs. i plan on running comp cams 68-232-4. Can i still use the mopar performance p5249464 valve springs even though they arent conical springs. and i think the 2001 valves have three grooves but the keepers listed to use with those springs are single grooved-p4529218. Any help on what i should use would be greatly appreciated.

Yes you can use the P5249464 valve springs. You should be able to use the stock 3 groove retainers. I do believe they are still 8 degree and should work with the MP retainers. Not 100% sure.

Also some of the early 0331 heads are known for cracking. I don't know what year Chrysler fixed them. So you might want to try to find out before you put a lot of money into the head.

Well i guess we will see. Ordering the retainers and springs soon and ill post when i find out. As far as my head it was fluxed and pressure tested with no cracks at 150,xxx miles. Hopefully they fixed it before they produced my head cause its already been resurfaced and got a fresh valve job with some new exhaust guides and seats.
Thanks alot guys.

The definitely DID NOT fix it in 2001. Supposedly it was 2003 of 2004 in which it was fixed.

The stock three groove locks are 8* and they will work with the mopar retainers, they are the locks I am using.

thankyou raptorfan

The older single groove radius lock keepers are 7 degree, this is for sure. So the newer three groove jeep stuff is 8 dgree, interesting.

The single groove 4.0 keepers are 8 degree. The 258 valves have 7 degree keepers.

So you have the
P5249464 - Springs

and the
P4452032 - Retainers

and you are using those with the stock valves and valve locks?

I just installed one and the valve tip is BELOW the surface of the retainer... that just doesn't seem right to me...

Now you're gonna make me dig through the shed to find the P4529218 keepers I used so I can compare them to the stock ones. I reused the stock valves, w/ a 3 angle valve job.

[lafrad]

well, not going to MAKE you...
I'm just really itchin' to get the jeep back on the road...

[lafrad]

Looks like that part number is a single groove lock...
Unfortunately I have the 3-groove valves...

[Bodo]

Do the older, single groove valves fit the later model heads?

[SilverXJ]

They do.
