Ok so I seafoamed my car, and while i was adding it into the brake booster hose, there was smoke coming out of the front of my engine, do i have a leak over there or something? i know its supposed to smoke in the back but the engine also?

Just means you have an exhaust leak. It could be through your cat or at the gasket whether it connects to the front pipe. Is there a lot of rust there?

If you seafoam it again, check to see exactly from where the smoke is coming. It may help to take off the manifold cover. If it's coming out after the cat, then there is a gasket that's probably leaking at the front end of the front pipe.

If it's leaking from the cat itself, it could be rusted through.

My all-trac dumps smoke pretty bad out of the driver's-side-most exhaust manifold runner, or, rather, where it meets up with the block. Is your mani sealed well? I don't care that mine leaks. Better throttle response and I'm just waiting for the engine to die.
