Lifter rattle at start up

Yes at 1.6.... 115lbs Im thinking valve springs causing a small amount of leakdown over 3 days...timed it at 55 seconds this morning before tappet noise stops completely. maybe just have to live with it i guess,,,
New lifters at 115 on the seat and they are taking almost 1 minute to bleed up?
I'd be investigating that.
