Engine builders...this machining cost sound excessive?

Hey guys. So I got my block and pistons back from the machine shop on Friday. Yesterday I started prepping the block following @krazykuda excellent build series and I found that the number 4 and number 5 cam bearings are turned in the block. The number 5 does not look too bad but it's difficult to see. The number 4 bearing is blocking approximately 30% of the oil feed hole up from the crank. I pretty much know the answer to this question already but is this a big deal? I actually had this happen in the past with the only other motor I ever took apart on a LA 360 and I wound up drilling up from the crankshaft through the cam bearing race and then I chamfered the bearing feed hole. I tried calling the shop today but got no answer. I will continue until I get ahold of him but what do you think about this?
I'd do something on #4 as it feed the passenger side rocker shaft. Your drilling and chamfering solution seems fine as long as the stuff is caught.
