Lifter Replacement
You need to remove the heads to replace the lifters. If you leave the stock lifters in place you can spin the cam and push the lifters into the guides.

WOW!!!!
Your in for a lot of re-work or worse,,,engine damage!! If he doesn't know how to lock the lifters in place, he is sure not going to know all the critical stuff about the harmonic damper installation and bolt torque procedure and front timing chain cover alignment stuff!!!!
You can use wooden dowel rods and insert them into two holes in the front of the engine. You remove the rockers, insert the wooden rods in the holes and spin the cam. The dowel rods will actually HOLD the lifters in place. I don't remember the actual size of the dowel rods (I think it was 3/16" DON'T QUOTE ME ON THAT!!!
) I will find out later tonight when I get home.
If if not too late, maybe you can back out of the repair and find someone who is LSx engine knowledgeable!!
THE HEADS DO NOT NEED TO BE REMOVED!!

Thanks for the concern, but I've known this guy for nearly 15 years and he's always treated me right and done excellent work with all my vehicles. The more I'm learning about this (from this website and others), it's not necessary to remove the heads to replace the cam, but it can be a tricky procedure. I have all the confidence in the world that it will work out as intended. The guy is not trying to rip me off by any means, but again, thanks for the concern
I'll try to keep things updated here as more information comes in. Then, you can either say, "I told you so" or "Cool, glad things worked out for you"
