I'd be careful about going over 72-75ft/lbs as overtightening can cause a other htings to change that could damage the engine. The 72 figure came from Reg Reimer in the US who did a lot of research and tension testing to failure and the like. I imagine the bolts can take more but several other forces need considering. The compression on the head will slightly distort the chape of the head and put more stress on valves and the like, but most importantly the compression on the bores will make them want to take an hour-glass shape, eventually starting to grab onto the piston. After saying all this it is likely that it would take quite a lot more than 80ft/lbs for this to happen - but I havn't done any testing. Do you know of any long term successes with say 80ft/lb? There in lies the answer I suppose. Just something for you to think about. Michael [Report message to a moderator]
