Jus a quick question...I have a 99 explorer 5.0( bottom end is THRASHED) but heads are perfect. I know i need to get better valve springs blah blah. but question is.. CAN i use the explorer exhaust manifolds on my car when i change the heads to the gt40ps? at least until i can afford some "p" specific headers for my stang? Like, will the headers bolt to my bbk offroad xpipe i have now?
