Been there done that. I lost one of the screws in the #7 secondary plate. The engine does not have to come out. I pulled the left side head found the screw imbedded in the head. Removed the screw cleaned up the little burs on the piston top and head with fine emery paper. There was no damage to the cylinder walls. While it was apart I had the top end ported and powder coated and re assembled it. You will need the crank positioning tool (I borrowed one). I used drill bits to position the cams. Read the book and take you time. The biggest problem I had was breaking the head bolts loose, Impact tool didn't work. I had to use a long breaker bar and pull til I thought I was going to break something. I have put 15 - 20 K miles on the car since the repair.
Good Luck you will learn a lot.
