Manifolds
nice. sounds like a good deal. from what I have read and herd. stock manifolds get more than enough flow for stock heads. so you should be alright there, unless your wanting some long tubes. I would just have them installed. and after a few hundred miles check to make sure he bolts are still tight and there aren't any leaks.
He's a friend of mine and a damn good mechanic so I trust him when he said the worst case scenario happened....it happens,I guess where the two bolts broke off was not the ideal position,he took the head to a machine shop and the told him to get a new or remanufactured one. That's why he paid for the new head.
