[QUOTE="swampratt, post: 3157743, member: 15054"] Most valve seats are induction hardened and if you install hardened seats you usually have the same hardness as factory seats unless you step up to stellite seats. I have never needed Hardened seats in any vehicle and I have driven many 50's and 60's engines and drove them hard. The trick to make them live with unleaded fuel is TUNE. DO NOT let the engine preignite if it is pinging get your foot out of it and tune it ..Pull timing or add octane. That eats the seats in short time.. run good air filters that seal also. Now if you have had those seats ground a lot then the hardness could be gone. Like if they were sunk and you ground them as sunken. If they are sunk now then the tune was off. If they are not sunk I would touch up the seats and run them. Folks machine shop in Norman used to be excellent many years ago ..then they got the 460 compressor contract and lost touch with the every day guy. Now they are back to their roots of doing excellent work. That is where I go. If I order .0045" piston to wall clearance that is what I get. They have a dyno and flow bench if you are into that. You can get adjustable rocker kits for the FE if you want all that. [URL]https://www.cnc-motorsports.com/prw-3239022-ford-fe-shaft-mount-stainless-steel-rocker-arms-42380.html[/URL] If it was my build I would do some milling and decking of the heads and block and port the heads and stick a 268H cam in it. If I was using it as a daily driver tow truck. If I wanted more power maybe a 280H or something like that and shoot for 10.0 minimum compression and a set of 370 gears at least. Years ago the 410 was the way to build the 390. Those parts are getting hard to find. I used to like anything but a chevy. [/QUOTE]
