When you take it all apart, have bolt cans labeled as to where it all goes back together. Take pictures before removing parts, the reference can't be beat. Take two old spark plugs and weld some 1/2" all thread to them and use them as your clamping tool it works great. The first time I did the head I used the longest head bolts and pulled it down slowly with them. I liked using the spark plug clamp best though.
Good Luck !!!RK
