hahaha sounds like someone is trying to fit a Automerter temp gauge in a LS1 head?. Can you believe you have to buy a special temp sensor from Autometer just for the LS heads!!! what a $21 crock of extra cash-flow!

Storm,, Wasn't trying to target teflon tape specifically,, just saying brass into iron and you really don't need anything. I've seen guys tap the pipe threads too deep with the tapered tap to loosey-Goosey, and then try to use 15 wraps of teflon tape to 'take up the space' . Then wonder why the gauge doesn't work. There are a myriad of sealing compounds and ideas,, none of them are 'good' for a electrical connection. But I do agree, Teflon tape (2 wraps like your supposed to do) is probably the least offensive to making ground. It only takes what,,,,,, 1/16 square inch of solid contact to make good ground.

No New alum heads for my 400sb have the small sender hole. My new autometers do have the small sender. Just have to get around to finishing my new cluster. Have ya seen the oil pressure gauge for the LS? That one looks like a PITA!
