I also think he has other problems. I dont think he's found the root problem yet.

I know when we running the big block in the dragster years ago we ran a flat tappit big lift cam. We gaulded a cam bearing one night on a pass (it wasnt pretty at all). Pulled it apart went through it, installed new bearings,new cam and lifters and went back together with it. It didnt even make through the break in period for the cam and did it again. Long story short we should have line bored the block the first time. Why it was out line who knows, when we had probably 100 passes on that motor before it all started.

Im not saying your block is screwed up...Im just saying before you throw money at it even with a hyd. roller....make sure everything is right. With the tight gaps on the cam bearings and lifter bores it dosent take much to give you problems.
