Defective lifters from Edelbrock

[JMD]

Hi all,
I'm halfway through putting an Edelbrock top end on my 454 (kit #2095) and I noticed one of the supplied lifters has a pinhole in the side. Almost like an oil hole, but only one lifter has it so I'm guessing it's a defect that somehow made it through QC. I know I should wait until I get a new set shipped to me, but it's a back ordered part so who knows when it will actually show up. Could be months...So my question is, am I out of my mind to use that lifter despite the blemish in it's side?
