Thank you all for the large amount of information! I am sorry it has taken me so long to update this thread, but after two deployments and not much time on my hands, I traded the 81 Toyota and sold the other motor I had. Now I have a 1980 with a 4in suspension lift, W56 trans and no motor. I was however able to get ahold of a 2RZ from a 95 Tacoma that needs a set of rings and upon my return from my current deployment, will be rebuilding the motor and putting it into my truck!
When you take the RZ head off, do not turn the head upside down don't remove the lifters they are not adjustable leave it be or else!
You'll need a w59 bellhousing now
