Re: Motor prep work
When I replaced all of the engine hardware I replaced one screw at a time so that tension was always on the gasket so I didn't have to replace them. I am talking about the clutch cover etc. Another thing to do is make sure the acorn nuts on the head are not bottoming out. Sometimes the studs are too long and so the nut bottoms out before touching the head. You can either shorten the studs or do what I do and buy regular non acorn nuts.
I am not sure what size your studs are. I think mine were 8mm but I have heard of 7mm. Maybe next time you are at the hardware store buy 4 7mm and 4 8mm nuts. They are cheap and then you can replace the acorns. Or just wait, I am sure someone here will post all of the stud sizes.
