Matt, couple of things:
Timing is 28 deg all in, about 14 at idle.
I agree with others that's to little. I'm running 36 in my FE, all in by 2k.
My laser temp gun shows 168 in the upper radiator hose and 135 in the lower.
What does it say that your manifold temp is right at the sender? I just found out that I was using the wrong sender and that my gauge was wrong because of it. i.e. if your gauge says 220 and your temp gun says 180 at the sender then you have a gauge problem, not a heat problem.
I've heard of people having cool lower hoses, not me. Could the 1.25" tubes be too big, and water going thru radiator too fast?
But your temp gun does show a 30 degree drop from rad entry to rad exit and it doesn't sound like it's that hot anyway. If your water temp is 220, then the water exiting the the upper part of the engine will still be 220 not 168.
Bottom line, with the temps that you've written I question whether you have a heat problem or not. Use your temp gun some more and see where you are.
