Installing Spark Plugs - Are they seated completely?

I'm changing spark plugs (autolite 3924) on my 95 mustang with aluminum headsI've heard the stories about plugs blowing out of the block from not being torqued down and I've heard about over-torquing them and ruining the threadsThe angles of the plugs between the header ports, master cylinder, egr tube etc, make it almost impossible to get a torque wrench in there so I can't tell by thatI can finger tighten to a point but still the plug grabs a bit to where you have to put a wrench on itSome say give it a 1/16th turn after finger tight but I don't even know if the plug is seated all the way or if I can't finger tighten it completely because of how my hand is positioned in thereSo with information overload paranoia has set and I can't really tell if the spark plugs are seated all the wayWhen I back out the plugs there are no metal shavings on them but they seem to keep turning and turning with a slight push of the ratchet even after hand tightening them Can y

Answer:

First look at the label on your yarn-how many stitches and rows does it say to make 2, 4 or whatever inches Next look at the pattern and look at the number of stitches and rows the pattern say the knitting worsted should makeNext-Do a swatch with your yarnIf the number of stitches are close use the same needle called forIf they are off by a bit use a slightly bigger needleCast on the number of stitches the pattern says should make that 2 or 4 inches and knit the required number of rows in stockinette stitchMeasure your swatchIf you need to change needles and do another swatch Once you have the swatch the required measurement then the whole sweater will be rightI often don't use the yarn called for and this system has always worked for me
The pattern you're using should tell you how many stitches to expect per inchDo a small sample patchSee how it works with recommended needles; use larger ones if it seems necessaryBut see how many stitches you're getting to the inch with the heavier yarnThis will tell you the adjustment that may need to be made to the patternNeedless to say, this can get a bit complicated and even confusing.
They shouldn't be too difficult to hand tightenDid you put some anti seize on them also? That should help, also will lessen that chance of blowing themand never take your car to the guy that said he uses an impact to put plugs in an aluminum head and when your done, do you wanna come do mine? in a f150 with a 5.4 ;)
