When my K was wet sumped I removed the foam (my foam sat in the sump & was not sandwiched between the baffle plate & oil rail) & fitted a Hellier baffle. Not a lot of difference with OP change to be honest. So dropped the sump again, drilled the holes in the sump gasket & modified the oil pick-up by putting 3 dents around the periphery in between the 3 blips. The blips are supposed to keep the pick-up from touching the bottom of the sump & the dents just increase the flow rate into the pick-up. It does work & stopped the OP gauge from waving at me.
When the engine was dismantled one big end bearing showed signs of mild damage & that was after 6 years of track days, road use etc., some 19,000 miles. Foam was removed & Hellier baffle used for 1 of those years.
