Always used acl bearings.
You can buy oem Honda half bearings for an arm and a leg but I've had good experiences with acl bearings.
Clearances were too tight on my b18c so I had to use acl race bearings to get them into spec, however on this d16y8 all main and rod bearings came into spec. On the tight side but nonetheless in spec.
