If your going to the trouble of importing Indian clone parts from another country why not get directly from the country of origin ??.
I have no connection with these people, other than recently buying a set of main and big end bearings from them for a genuine Lister CS16-2, and can only say that they were very accomodating of my reqirements (I wanted a Lead Indium centre main, and big end shell bearings instead of the usual white metal), and there product was of excellent quality. The engine these parts are fitted to now runs reguarly and has done so for circa 6 months without any problems.
The only downside was the delivery took a while, but this was compensated by the 4:1 price difference between them and SEP.
They are also most proficient with custom delaration forms as well
