What are your opinions on older heads and non hardended seats. I have heads with a 1973 date code I assume the seats are not hardended. Is it worth having these redone and not replacing the seats or should I scrap these and get some newer ones with hardended seats? from what I found out from the machine shop is the cost to replace the seats is about $160 for 2 heads, Add in a valve job and Its near $400 for the pair. How long will non hardended seats hold up with unleaded gas?
