Missing Options

[Bullet]

I got the engine started tonight. And as it was running it was missing bad as if though it was running on only 3 Cylinders. But as i take the RPM to around 3k it starts to run really smooth. I cant help but to think that i might have a Fualty injector that is having a hard time opening up untill there is some good pressure behind it. I havent had the chance to Check for spark at all the cylinders or do a spray check on the injectors. Im just trying to get a plan on were to start first.
Also the right bank has a exhust leak that is comming from the head to headers I can look up and see where it left a dark spot on the Copper caskets. Have any of you guys tried exhuast sealent (it is a copper color) to try and fix this. and yes i checked the torque on the studs.

I went out and Bought a dwell meter today. Chacked the dwell first thing at it was at 50. after using it I would much rather use the meter then the Feeler guage.
I fixed the exhust leak today just by removing the right back header and using a file like you sugested and retightned the header bolts in 1/2 turn sections to ensure even pressue on the gaskets.
Also the crapy running was fixed my a missplaced Vaccum hose. Im still fighting trying to figue out were all the hoses go. I removed the Air pump. and the diagram that is from pelican parts shows stuff i dont have. But i hope that just through Trial and error i will finaly figure it all out. Then im going to make a diagram just so i dont have to go through this again.
Also i foun that my Throttle pedal is stuck. If i push The pedal in it does not return, I have lubricated the heck out of it and still same problem. Has anyone ran in to this before and found a fix for it?
