Default LEAK coming from my exhaust ports! What's wrong?

I haven't drove the truck much since ive finished the cam install and all the other mods but have never had a leak when it was running. Today i was letting the truck warm up so i could see if the electric fans were working correctly and i noticed a small puddle on the floor. So i felt of the liquid and it is an oily substance, but it doesn't have much of a color. So then i started trying to see where the leak was coming from and it was dripping from the rear of my headers, then i looked closer and saw a drip coming from the next to the back exhaust port. What would cause this and how can i fix the problem? My dad said maybe i had a cracked head but i don't see how or why it would have just started leaking today.

my header gasket? i used Percy's Alumaseal or something like that. They're supposed to be guaranteed to never blow. But anyways are you sure about that? because i didn't think they're is supposed to be oil or any oily substance coming from the exhaust.

USe Stock gaskets, they seal REALLY GOOD

but that oilly substance is a mix of condensation and the crap that sits in your exhaust ports (carbon, a smidge of oil, etc)

replace your gaskets and watch the problem vanish

yea there is some oil substance in the exhaust ports like zzebes said is carbon buildup and condenstation. i was wondering about the gaskets bc the stockers are the best out there just replace em and you'll be good to go.

Also check your valve cover gasket, it's easy to pinch them and have a little bit of oil seep past and down the back side of the block.
