Just slapped on a set of ported out stock manifolds that I had. Wanted the MS sets but don't want to wait. I really wanted an aftermarket set of manifolds but didn't want to wait or put on an inferior product that I will have to swap out eventually due to stress cracks. I will probably pull the engine again after summer or so and just swap them out for a set then as well as a few other things that I don't have the time/money to do before ZCON. I don't know....we will see.
