New headers are in and look great. They were about $200 shipped to Canada.

They will fit with out too much trouble, but i will need to set my engine back roughly 2" so that means new adapter plates. There is lots of room for it and i dont have much else roughed in yet. Im also thinking the farther back the engine is the better for balance etc.. Im going to order these

They're adjustable so i can get it in the perfect spot.
