Re: Aluminum heads -- spark plug torque

["Simon Matthews" <simon_atwork@hotmail.com>]

I remember being told (or reading) that one screws the plug in until the 
gasket is toght aganst the head (not but not compressed), then give the plug 
a 1/4 turn to compress the gasket. This only works on brand-new plugs, 
though! Any comments on this?

Having fitted plugs into aluminium heads, I would think one would have to be 
over-tightening rather drastically to strip the threads.
