Maybe that was your problem. Next time try some jack Daniels or some Percocet.
Just saying. Your gonna had a bad time if you do the above.
On a serious note. Losses it all up. Shake it a bit so all the joints move. Snug up the header to the block but don't fully tighten it.
Make sure you tighten the studs like a tire. Keep the pressure even so it's nice and flush. Now that your perfectly seated on the header you can finish tightening them. Keeping the pressure even. (Like a tire)
Now that the headers snug and perfectly fit. Shake the collectors a bit to get them in the proper place this time. Tighten the collectors and go hulk on them off need be. I know it's hard to get in there but get about five foot of extensions and a good breaker bar so there nice and tight. Just don't over tighten them and strip any thing.
Ps I'm not to be help responsible for any drug or alcohol abuse/injuries if any occur from the instruction in this ridiculous post.
