From cylinder #1 @TDC on the compression stroke and adjusting #1 exhaust and intake, the crankshaft is rotated 360 degrees to get #4 @TDC...is this correct?
To adjust the valves each piston should be on TDC but you can adjust the valves in other ways. Look in the manuals and source info section for a first gen manual. The process is the same for nearly all engines. When the engine is on #1 TDC you can adjust other valves same with #2 and so on. But if you are unsure then the best way to do things is 1 at a time. You will rotate the crank 2 full times to make all the adjustments this way.
Mr 4d55 supply
with number 1 tdc adjust exhaust 1, 2,3 and Intake 1
rotate crank 360 (Timing mark on cam will be off 180) adjust Exhaust 4 and intake 2,3,4
Are you guys setting the valves when the engine comes up to temperature? Or when it is cold? Also what size feeler gauge? I am told it is better to error on the loose side rather than to tight. Is this correct? Thanks
...just like that
news to me but def. good to know. im curious, are da valves adjusted closer to "perfection" if done one cylinder TDC at a time? or makes no diff. and using the method u mentioned produces great end results as well.

I may be a little late but I thought I'd post here anyways. How I do it is:
From what I recall the gap (in inches) is between 0.0012-0.0024 on the intake and 0.0018-0.003 on the exhaust (I think I have the intake/exhaust the correct way around). I turned my crank pulley bolt until the rocker arm on #1 cylinder intake was as high as it would go, right before it starts falling and then I set the exhaust gap. Turned the pulley bolt until the Exhaust was as high as it would go and I set the Intake gap. Repeated that for the remaining cylinders.
