On ebay, hemi quest.   http://www.ebay.com/itm/261597156336   Jimmy

If compression test results are with in spec per service manual. Can the head still be cracked and leak water and not cause low Compression test results? ? ?

Probe requires a 1/8-27 hole/tap to install. Putting it in the exhaust manifold under the turbo is the plan. Has anyone else used this location? Would it make the exhaust manifold prone to crack? It will be stress relived and all casting flash, numbers, and probaly heat sheild mounts removed. Plan on covering it with header/heat wrap. If it isn't a good location, guess downpipe. Thanks for all your input and suggestions. lenny
