Thanks for all ypur help. Last night I figured out the problem. Of course it had nothing to do with the headers, The coil was bad and jumping spark. Replaced the coil and starts right up. Still dont know what the noise was/is since it fires immediately. Sorry to be a pain and again appreciate the help

Thanks for getting back to everyone on this. I was going to suggest that it was electrical or fuel related because a header shouldn't prevent an engine from firing up...

Yes, it's good to get confirmation of a result.

Some don't bother.
