Do realize that the VQ engine uses solid lifters and the time to replace just one bank is 16.7 hours, book time? I've never see lifters fail in a VQ engine; may I ask why you are replacing them? The first step would be to measure the clearance to see if you even need to replace any. If any are out of spec, you need to figure out which size lifter you will need (there are a lot of them) to get your clearance into spec. Then, since the lifters are shimless, the camshaft will have to be removed to replace those lifters in need of replacement. It's a big job, so make sure you know what is all involved before attempting this!
