Replaced the cam bearings, installed the cam, cleaned the heads and block, installed valve springs/retainers, reinstalled the lifters, LS4 oil pump, and timing chain.  It took a few days after work to accomplish this, hopefully it’ll be all together after this weekend.

I took a few pictures to show the difference between the stock valve springs and new ones, they’re MUCH beefier and even taller.  I also took some pictures to show the difference between the LS2 chain and LS1 one.  I scraped the heads and block down then did the rest by hand with scotch bright.  You can see how bad the block was in the picture of the cam being installed.  I can’t wait to get this thing running!
