Is it possible my headers are causing a hard cold starting problem? Its hard to start on the old motor and the new one it never did this before the headers only after I put them on

How is it acting? Is it laboring to turn over, cranking with no fuel..?

yeah its kinda labouring it turns over but is super rough and when I give it a little gas it dies then I start. It again and its fine like its almost flooding that's why I was wondering maybe its over fueling? Its only the first start of the day the rest of the day its perfect

Mine used to do the same thing. Turns out I have a fubar'ed regulator. Check you fuel pressure...
Also, if you just installed headers you may have screwed up the ECT sensor. If the ECT sensor is messed up the computer will think it is at the wrong temp and give it the wrong amount of fuel.

computer doesn't really read many sensors right off the start...usually takes an initial warm up period. I would lean towards vaccum leak/fuel issue.
blown transmissions are about as useful as 97% of the guys on this forum

hell i guess it looks good to me? im not really sure what im suppose to be looking at on it but all the sensors should be brand new including front o2s and anything else since i had everything replaced when the new motor was put in about 3 weeks ago
