Runs a bit hot, and diesels like crazy

I don't get it, I just finished swapping an e21 head, new headgasket, brand new ignition, newer radiator, newer thermostat, newer fan, new fan belt, new weber dgas 38/38, set the timing, runs smoothly but it just ends up somewhat over halfway on water temp gauge while cruising, then ends up about 3/5 of the way at the gauge by the time I shut the motor off. Then it will diesel a bit (2-4 seconds), if I let the motor idle after putting it in park it will get even hotter. Its only about 55* outside. I notice there's a bit of smoke/steam coming from the oil cap if I remove it shortly after it was running. I have all of the smog water hoses disconnected, I'd use my heater but the fan doesn't blow when I turn it on (something I'll work on fixing before winter!)... what else should I do or check to remedy this problem? What exactly causes the dieseling (rumbling after ign is turned off)? Thanks..

What If I were to just seat of the pants advance the timing (no timing light), since retardation causes an increase in exhaust temp, hence more heat in the motor...?

The new radiator isn't clogged but I may run some flush stuff through it anyhow. I set the valve clearence to .08 if I recall, it was from a bmw 2002 manual. Should I loosen them up? Thx

After you switch off the key, the ignition system has no power, so there are no sparks. How could timing have any effect under those conditions?

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
