EGT location question, Jake? Options

[SpecialK]

My '73 (carbed/Web 86 cammed 2.0L) will be sporting 4 EGT probes and 4 CHTs (one for each cyl., got one hell of a deal on them plus I read the "dropped valve seat" post (IMG:style_emoticons/default/icon8.gif) ). I've got one Westberg combo EGT/CHT gauge and a 4-way switch. The mfg. says to mount the EGT probes 6" from the exhaust port, but I'm running heat exchangers. If I mount them at the end of the heat exchangers just before the muffler flanges will I render them pretty much useless for tuning purposes, or is the temp drop at that end of the exchangers insignificant (again, for tuning/monitoring purposes). I'm afraid if I install them up by the heads, they'll be vulnerable to road debris, i.e. - semi retread rubber (A.K.A - road gators), critter's, assorted crap that flies out of Redneck's trucks w/o tailgates, etc...

Also have an A/F gauge I was going to install, but that would probably just be overkill (IMG:style_emoticons/default/rolleyes.gif)


As always, any input is greatly appreciated (IMG:style_emoticons/default/beer.gif)
