well if its running fine, maybe you have a clearance issue and your headers are hitting the body somewhere and thats what you feeling?

It would idle like junk if the firing order was off. What all did you remove when putting them in?

if it feels like it's dramatically slower at WOT then you probably mixed up the firing order. I did that when I installed mine and it took me a day to trace it to the firing order.

I bet you may have cracked a spark plug if you didn't remove them when installing the headers.

Id start by replacing the plugs. If you droped one it may have damaged it.
