Help with 2.0LR build
 

Hey Guys Im doing a 2.0LR build for my car and so far I have all parts needed.

My question is will the 4g63 block need to be modified for my GRP aluminum rods to have clearance? Reason im asking is a friend of mine told me it would.
So can anyone verify this? and posibly send pics if that be the case.

I previously had these rods in my 2.1L setup with no issue with clearance for the rods in the 4g64 block.
