Eagle SIR6123CB rods differences from stock oiling

I bought a set of Eagle SIR 6123CB rods for my sons 318 build. Now that we knocked the stockers out of the block I noticed theres no oiling squirter holes in the big ends compared to the stockers. The stockers had these grooves to squirt oil at opposing cylinder walls. Is this something that should concern me?

Everything I have rebuilt up until now used reconditioned stock rods. It's just not worth it reconditioning stock stuff anymore. Is this something I should not worry about? I imagine this type of groove just makes the rod weaker. Anybody on here that can speak from experience of longevity on an engine rebuilt with these rods without oiling squirter grooves, or are my fears overrated and it doesnt make a **** that these oiling grooves arent in there. I'm mostly a body and sheetmetal guy, but have been known to build a number of engines and transmissions without any issues Heres pix.

Thanks
Matt
