Was supposed to pick my block LQ4 up from the machine shop today, but they called and said the cam bearings they were sent were too big. They told me they were for a car engine and different from my LQ4. Is this true? Anyone have a proper part # for LQ4 cam bearings?

There was a year-model break, not an application difference. Will be Durabond CH-10 for early design or CH-23 for second design.

Look at the head bolts holes. Use Durabond CH-23 or equivalent if all of the head bolt holes are the same depth. Use Durabond CH-10 or equivalent if they are not.

Can I tell from head bolt length, or do I have to look at head bolt depth in the block, I know mine uses 2 different length head bolts, but the block is at the machine shop where I can't go look till Monday....they did say the bearings the got were too big, from what I read 1st gen was smaller, I must have a 99-02 block

I have a 2004 suburban with different length head bolts and second design bearings. I measured the bearings to be sure.
