WTB:Built BP or BP4W head
 
Good evening,
I blew up my motor and ideally I'm looking for someone who already has a built 1.8 in the midwest. OR a BP4w head. Located in STL, willing to travel. Show me what you have!
Thanks

I have a BP4W head and valve cover in the Nashville, TN area. It does need some assembly as the valve springs were removed to swap for stiffer ones. I will check tonight if I have everything to put it back together. I also have a VICS manifold with the butterflies intact. The upper is ported for a Skunk2 throttle body and the larger vacuum ports (for brake booster and PCV) on top are now tapped for NPT adapters.
