Many thanks to all responded. I already bought the trimetal
King/County bearings and after a short chat with my machine shop I am
confident the bearings are ok. Also Ahead4Healeys and AH Spares sell
them, so they should be alright.
My machine shop also mentioned they measured the bearing diameters as
they also have their experience with County bearings and grinding the
crank journals according to the bearing diameters.
Otherwise they also see no reason not to go with them.
So thanks to all, I am now relieved and go forward with the bearings
I have. Josef Eckert Konigswinter/GermanyAn:

I am using ACL mains and King trimetal big ends and so far nothing
has exploded after a few hours dyno running. The colour of the
bearings is an indicator of whether the Kings are bi or tri metal-
dull grey as opposed to light aluminium colour for the bi-metal from
memory.
The King bearings had quite a number of small lumps on both the back
and front faces which I gently scraped off and smoothed with 1500 grit
sandpaper before installation. The ACL's went straight in.
More important than the manufacture of the bearing is the clearance
and I'd strongly recommend determining the installed bearing diameters
before grinding the crank. Mine were all on the bigger side of ok so
the crank journals are ground between 0.06 and 1.00 thou bigger than
the max book spec to compensate.
