I figure for $250 it would be nice to have but I was wondering how much of a difference would changing the manifold make? Also how much time and how hard would it be to take the stock one off and put the aftermarket one on?

Thanks,

Chris

 

on stock heads....nothing. People pull the intake all the time to do the intake manifold gasket fix. I'm gonna be doin mine in a couple weeks...
