To-day I took another look at the head temps.The READINGS from the aluminum and around the plug are in the order of150 F. The black Allen head cap screws showed 225F !!
Many years ago( when worked) I had some experience with I.R pyrometers and found them difficult to use. Thanks to all for the replies -they seem to support my thoughts. The reply from Ed was just so funny and so right .LOVE THAT MEAT LOAF .
