Well I decided to take heads off and look around.so far only have the pass Sid head off but gasket looks fried but cylinder walls look good. I was thinking about having the heads tested and maybe ported depending on what you guys say.

After breaking off a egr bolt in the manifold I was thinking about a set of headers and high flow cats. The part store has a set of long tubes for 250. I was also thinking about cold air intake and bigger throttle body.
