They're being fixed by a local shop . Patriot told my they would fix them for free, replace or refund my money. It is costing me about $600 to have them fixed. If I got the heads refunded. It would still cost me the same amount of money to get some good heads. If I send them to be fixed by patriot. They could be f__ked up again. I can't chance that again.The problems: One guide's hole was big enough to have had the next size guide placed in it. It was very loose. I have'nt found out about the rest of them yet. The valve job was'nt good at all. The guides for the exhaust valve didn't have enough clearance. The valves were stuck in the guides. I was making good power the way they were. Once I get it back together it should make more power. I will say the heads are cheaper, but in the long run they are more expensive. Once you add all the labor to pull the engine and have them pulled off , fixed, installed and reinstall the engine. Maybe you guys get the point. I do wish I would have bought different heads in the beginning. I guess because this other shop is redoing my heads that will make them not be Patriot any more. What a headache these heads have been.
