in the old dodge engines exhaust manifold bolts came out very easy does anyone know if the ones in 2004 hemi are the same or is it a job that should go to a service centre I am missing the heads on two bolt on the left side part 2 is there an up graded bolt for the manifold

 

Aluminum heads, I'd opt to take it to the man... I'd turn it into an excuse for a set of headers though...
