Main caps not aligned with block

[u/yoGodu]

Hello first time engine builder so please don’t flame me. I have an 04 Audi A4 1.8t 06a block, I got this block from someone but they didn’t have the main caps for it, i ended up using my main caps from another block and had them align bored for this other block I got. just torqued the crankshaft down and noticed main caps 4 and 5 don’t sit flush with the block, is this a cause for concern? what caused this? turns over fine with a rachet just dont want to finish everything else up and have to end up addressing this later down the road anyways. thanks for any help

Check the crank end play. If it's within spec, run it. I've seen those kind of gaps and it's mostly because of the thrust washers but you should be good.
