I was finishing up my h22 build. I have built 3 or 4 b series engines. on the main bearings on a b series you have a upper and lower bearing due to the oil holes. On h22 they seem to have the same bearing for upper and lower. I have looked on the bearing i see no u or l. so i just installed them because i cant see any different. did i do this correct need to know so i can take the engine off the stand in to the car this week

 

About the bearing i have a set of new 55mm h22, oem f22b1 and acl h23 bearings. I also have the bearings that came out of the f22a i am building.they all look the same so just assume that H/F series main bearings dont go in any certain way. I guess I will see what happens.
