Default Fully Grooved Bearings

Would I have any issues using fully grooved main bearings on a mild 400 with a factory reground crank and melling high pressure oil pump? Reason being, I bought a set off of ebay for cheap thinking they were the half grove but as luck would have it...

Thanks

They will be OK in a mild build.
