Recently got the block back from the machine shop bored .5mm over and honed. Intigrated engeneering rods .5mm over lower compression pistons. New bearings rod and main new thrust washers. Polished the cranck shaft. During assembly it gets extremely hard to hand crank over. Once it goes it sticks when cylinder 4 and 5 get to bottom center. Disassembled everything and checked all components reassembled and once I installed cylinder 4 it was smooth but still minor stick once I installed the rod and piston for cylinder 5 it was extremely difficult to turn over. I'm at a loss any input from a knowledgable person would help. I checked the tolerances and they were all .076 for the main bearings.
