Anyone know of any 10 degree valve locks for the 6.4 triple groove valves? Can find single groove for the .3125" stems, but not triples. Any help is appreciated!

PAC spring and retainer. Retainer is not available in 7 degree.

FWIW, I run stock retainers on my Manley Drag Pack springs with Manley locks.

I assemble a lot of heads for LS stuff and its all been 7* for the past several years and haven't had a problem. years ago, there were a lot of spring kits with 10* but I never see it any more

I'll be using stock locks and Comp moly retainers on my Manley springs. I dont think there is much choice when running stock valves.

The beehive spring I am using has a taller installed height for the longer valves in a 6.4 head and is a little larger in diameter, both top and bottom. The stock retainers are too small. Matching retainer is only available in 10 degree. May have to have some 7 degree retainers made for this spring and use stock locks.

Ok, i see why your having a problem. How big of a cam are you planning on running?

Your combo sounds like it could be interesting

Staying conservative to start, .620" lift 267*-273* @ .050. Geometry isn't the best at .650 lift, so taking it easy to start.
