At the end of the good weather season I had a problem with one of my crane gold roller rockers and it died a sad death. I'm looking for another set now and came across the 440Source roller rockers for what seems to be around half the cost ($320 incl. shims, spacers and alum. hold-downs) compared to other name brand roller rockers that are in the $600+ range. Cam is a .545 lift hydraulic flat tappet and I'll be installing the Comp 924 springs, so spring pressures are pretty moderate. Does anyone have personal experience with these (quality/longevity)?
