Are hardened valve seats necessary?

FRPP is Ford Racing Performance Parts. Their phone number is (800) FORD788. You can download a copy of their current catalog at http://www.fordracingparts.com/home/home.asp. Go to their menu bar and it is the top right far right hotlink. Good source for parts. Be sure to buy from Steve at Tousley Ford. Tell him you are from the Modular Fords website and he will sell you the parts at 10% over cost.

<edit> Not that it costs anything but to be perfectly legit you might want to join the Modular Fords website www.modularfords.com they are the ones I know have the deal with Tousley Ford.

I just finished rebuilding my engine. I have open chambered heads in a '71 Cleveland. The heads had hardened seats or I would have installed them. As it is, I went with Manley valves and Comp Springs. It's a sad thing when an engine starts loosing compression because of a burned valve or seat. I've heard of guys rebuilding Clevelands and other motors without hardened seats with no problem. I've also heard of more motor that lost compression because of burned valves and/or seats. Why risk it?
