Clevite 77 engine bearings [Merged 3-8]

[AlphaVision]

Hello, sorry for bringing this up, but I have the 0.0027 clearance with clevite main bearings. Can't measure the clearance with stock bearings though. So I don't know what to do...should I stick with those or get oversized ones and target 0.002 max clearance?

So after reading this thread i think the tri-metal is better for high hp but the ACL Aluglide is aluminum plus tin and silicon, if im not mistaken. Would that be better than straight aluminum or tri metal? Also is the ceramic coating actually that helpful? Right now im between these three and coating or no coating.
