I dont know if this subject was brought up on this website or the other one I use, So sorry if Its a repeat, I am just wondering how long aluminum (AFR)heads would last on my strip/street motor? this engine plans on seeing some very long road trips so can anything go wrong in the long run?

I've seen a set of aluminum heads look like destruction hit one cylinder and they still fixed it. Amazing what they can do with aluminum these days. I don't know how long they last but I do know they are a bunch easier to repair than cast iron. JS

There is "almost" no such thing as an UNrepairable aluminum head these days.
Iron heads are still very difficult to repair or weld.------------------

I'm a self-taught welder, never had any formal training (which basically means I can stick two pieces of metal together  )Just how do you weld cast? ------------------

It can be welded, i've seen 426 Hemi iron blocks with whole corners welded in. It is best done with the block heated, but can be done cold and slowly working 1/2" at a time and peening the weld till cool.It can be time consuming. I've fixed my cracked 427 block that way.
