Contacted this company through eBay and they would only refund about half the cost of the gaskets despite losing 15 hours labor and well over $150 in oil, antifreeze, filters & etc. Even after setting them several detailed pictures showing the defective part of the gasket on the new not rebuilt not used new brand new cylinder heads OEM from Ford all they did with jerk me around every time I contacted them there'd be another hoop to jump through or different instructions waiting me out. Avoid their head gaskets at all cost! Installed new felpro gaskets and no problems! I am a career mechanic and certified vocational Automotive instructor and sadly I knew better than to buy off brand head gaskets but wanted to save a couple bucks as the plan was to put my old heads back on but turned out they were cracked and not rebuildable. I would never buy from this company again after my experience with a defective $60 head gasket set.
