Latest update,

I drained the fluid and pulled the sending unit and checked as best I could the water passages around it. Head is clean and I could easily blow air into the head and out through the radiator / from both the sending unit hole and the pipe that connects to the hose going to the heater. I removed the thermostat and tried a number of combinations of blowing air and plugging holes, couldnt find any type of restriction. At one point I blew ino the head and forgot that the only way out was through a heater core full of coolant....can you say "Prestone shower"...damn that stuff is sticky.

I have a feeling the the guage in the car may be bad as well as it was reading 20 degrees higher than my IR unit. So a new one is on order.

I checked the timing and it is sitting at 12-degrees BTDC so next weekend I plan to back that down to 20-degrees.

I think the electric fan thermostst in the radiator comes on at a higher temp as well. So I will look for one with a lower start temp.

Thanks again for all the great information.

Cheers
Rob
