Anyone using the 440 Source Hydraulic Roller Lifters?

Have you figured out your problem yet. I hope it wasnt/isnt serious. Has 440 source got back with you, they better I'm watching to see there response and i'm sure others are too, Im getting ready to purchase some heads and a stroker kit and I wont use them if they dont stand by there products. Good luck.
Their stoker kits can't be beat, some of their lower cost products need some modification for example..... I had to grind a little off the end of my distributer for it to fit in their bronze distributer gear....I had to also take some off of the other end (shaft) so that it would slide easy into the oil pump....
