6.0 Avalanche

I have a 2007 Avalanche 4x4, how long should it take by a auto shop to remove both heads to replace lifters ?

Book time on that is in the 20 hour range. I couldn't tell you specifically what the exact number is. It's ALOT of work. Definitely more work than it should be. Thank GM for that one ...

20 hours can mean you are without a vehicle for a minimum of 3 days, likely taking 4 days.  I can remember bitching about having to pull the intake on the B/RB Chrylser engines to change lifters.  They were a dry intake manifold, didn't have to pull distributor or even drain rad.  Intake gasket was turkey pan with no paper gaskets.  Can't imagine having spend over a day just to get it apart.  Its likely just as easy to pull the engine and do the work on the bench.

I honestly hate the LS engine for this reason (and its failure prone lifters, cam bearings, cam, VLOM, springs, etc., etc., etc.).
