OOps, left the timing chain in too long!! Now I need to fix the left head. Never having done this on a 560, HELP! I've done head work on lots of 6's and 4's and a few Chevy v-8's. So I know the general process. And I'm hesitant to try to pull just the left head, but I also know there isn't much room around theos headers.
What can go wrong that I should watch out for?
What extras should be done while I'm in there?
