ls3 valve spring issues I am building a 6.0 with ls3 heads I bought comp cams 54-458-11 its 227/235 at .50 .614 .621 at 113. issue finding valve springs for it I bought 26925-16 .660 lift springs and they wont work any one had issues with springs on ls3 heads? It appears that installed height is 1.760 ish and other ls springs are 1.800. D they make a retainer to compensate for this? I would like to run a beehive sping but looks like they all stop at .625 need at least a .650 lift I think. Thanks for your help guys in advance

Machine shop said installed height was to low and new ones were higher. I think I may have found a kit from lunati LUN-73925K1LUN .660 lift with retainers, we will try it and see if it works.
