Just wondering which is more accurate for measuring temperatures, a temp. gun or an onboard temp. gauge? Or are they both o.k.? The old spit and fizzle method is getting kind of messy.

Temp gun will be more accurate 90% of the time. Check out the Exergen probe (distributed by Paris Racing) I have been using it to tune my gas cars for years, best temp probe out there by far.

A temp gun is not nessasarily more accurate than a temp gauge. It depends on how it is used. I have always used an on board temp gauge, and have had no problems. According to MIP the loop should be either between the last two fins on the head, or just under the head. The first method is the one I use. If you put the probe around the engine case just below the head as some suggest (including Venom) you are reading somewhere between the head temp, and the case temp. This can cause your temp to vary and You may or may not get a true reading. If you put the loop around the last two fins of the head, as shown in the MIP instuctions you will get a more accurate reading.
