definitely verify with the number on the block if you can, the only other way is to pull the heads and look for dished pistons. You can also insert a coat hanger or borescope into a spark plug hole and "feel" the pistons.
I got an LQ4 when I paid for a LQ9, definitely sucks to find out you were running 8.5:1 compression (thick graphite gaskets) on a cammed 6.0 LOL

[QUOTE=SSLSX427;14213498]do you know the pn#
there is no pn#. Only way to tell on mine was to first look at the top of the piston with a small light. You want to see a flat top, no dish. You can also scrap a piece of plastic zip tie across the top of the piston to FEEL no dish.
The other way to know for sure without removing the heads is to remove the oil pan and look for full floating pistons.
