I know this is really not a great idea, but I used a deep ratchet to put them in since hand screwing would take years!

I just was wondering, how would I know if I have over torqued or under torqued the plugs. I dont wanna have tightened them to much that next time I gotta pop the valve cover becasue the plug broke off or what-not.

Thanks.</td></tr></table><span id='postcolor'>
There's nothing wrong with using a hand ratchet to install sparkplugs, that's the way it's normally done. Screw them in until you meet some significant resistance. Then, if the plug has a washer (which ours do), tighten it an additional 1/4 turn (90 degrees).
