I am going to get that clutch kit, and I would like to go ahead and change the head gasket and possibly the oil pan gasket while I have it out. What about the timing chain, should I go ahead and pull all that stuff apart and replace it as well? I just plan on using this motor long enough for me to rebuild my 87 22r. Anything else that isnt to expensive or hard to replace that I should before I install this older engine? I hate to put too much money in it, since it is just a temp.
