hi, i know this subject has been beat to death but i still have some questions. the '07 cam plate as well as the se conversion kit (orange plate) have no bushings in the plate and the cam ends ride on just an oil film. has anyone seen wear in this bearing area? it seems like a high wear spot. the se plate upgrade for '07 (black plate) looks like it has bushings. if this is an upgrade can i just use that plate and build my own kit? i've read so much about this that i'm goin' cross-eyed but these questions still remain. thanks for your time.
