older dart 360 heads
I have a set of older Dart 360 heads..and i had to have a few valve guides re-pressed in the heads due to they lost there press fit.
During the conversation with the builder he claims these heads are on "there way out".
My question is.. the way i see heads are they are a casting with other components added to them.
Am i wrong here thinking that the aluminum isnt going to go bad.. unless u have some catastrophic failure which damages the head beyond repair right? All the other components the valves the springs,guides, retainers,locks..all are replaceable.
How is a head on its way out?..if it hasnt had catastrophic hole blown in the head?..and all the components attached to the head are repalceable?
I know the heads are older lower technology but they seem to get the job done.
Your thoughts would be appreciated
Thanks
Keith
