the ad does say...

Block:

""Seasoned 360 LA Style block"""""
Square and parallel decked
Align honed main bearing bore
Cylinders are sonic tested for thickness
Cylinders honed on a computer controlled machine to within .0002'' straightness and roundness

5/64 ring instead of 1/16??????

It says LA block on the JEGS ad but on the Blueprint web page it just says seasoned 360 block.

It had 1/16" rings instead of 5/64"... That's why they were loose in the ring groove. Sorry I mis-typed earlier and said 5/32" rings when it should have been 5/64" rings.
