Post is it vapor lock?

right now with the weather cool, my car is running like a pro. but i know carburetor cars run better in cooler weather but its never runned this good even in cool weather. when it is hot outside my car don't run to good. it runs sluggish and seems to bog. i might know what it is but not for sure, i believe that my fuel could be vapor locking thats causing this, i have no cowl induction for fresh air and i run headers. they are not ceramic coated in hot weather my car runs around 210 degrees. could this be my problem or something else. if it is what are some ways to help it.

All cars are affected by heat and humidity, no matter the brand or type. Try to give us some clue about how much of a difference so that we have somthing to compare to.

well before i put headers on it, it ran smooth. now when the weather is hot it don't run to good like it wont take the gas, i know that it should take the gas i have all new accel ignition system: wires, cap&rotor, super coil, module. so either the headers are causing the fuel to get hot or i heard that headers make a carb lean could this be it. it runs fine at night or cool weather.

Cool

Had a problem like this with a poncho 400, fuel pump was changed and problem went away. Also you might want to recheck that timing. Running temp at 210deg sounds like the timing is advanced a bit. Changing to header should not make this kind of difference.You could check the routing of the fuel line just to be sure the headers are not to close and boiling your fuel. Bench racing IS fun.
