After searching, and serching, and searching, i finally decided to go ahead and put the engine thats in pieces(probably missin some) back together. Before i do a couple Q's.
1. How can i clean the head without bead blasting it and without damaging it?
2. If i bore it out .020" do i need to have the head machined bigger too?
3. Any tricks in reassembling it?

All help will be appreciated, and this is the bigging of a good project, because there are very few MR2's whee i live. Ill try to take pics step-by-step.
