Forgot to mention, you should probably get new cylinder head bolts too. I
was doing mine "on the cheap" given the mileage on my Amigo and what I
paid
for it to begin with, but I had 3 bolts that I could only complete the
last
step of the torguing sequence to about 75 degrees before I stripped the
torx
head bolts. That, and the fact the the bolts are designed to be installed
only once because they stretch while being tightened, and it's a pretty
high
stress (hence stretch) they endure during the tightening sequence.
With the amout of abuse this engine has suffered and how little it has
cost
me to repair it, I'm very impressed with design and manufacturing of it.
