This particular engine had the GT head, so it has the bigger valves and all that. They completely rebuilt the heads, but when they rebuilt it, they didn't put hardened valve seats into it to start with. So it burnt the valves fairly quickly because it's over ten and a half to one to compression. They went in and fixed that, put tapered stainless steel valves in it and guides and all that stuff basically redid everything they did originally, but with hardened seats. When they didn't ground the valve stems to the correct length, so they weren't even opening or closing all the way and I couldn't get over the counter push rods over the right length."}
