I believe these King Tri-Metal bearings to be the best bearings available for Triumph six-cylinder engines.  As with any bearing, it is important that proper clearances are achieved.  The factory had a tolerance range for the bearing housing bore as well as for the crankshaft journal so clearances can vary slightly even when everything is within factory spec.  Always check clearances when replacing bearings.  Before regrinding a crank, measure the ID of the bearing when installed and grind the crank accordingly for desired clearance.
