Magnum heads worth the effort?

If you LA heads are stock, you'll see a gain.

IDK. Honestly, if I gave my speech on this it would derail this thread. But let me say this, my original plan, 3 years ago, was to put the 318 magnum in my '74. These heads were going to be direct replacement and I was only to have 300 into them. These were NEVER bought with intentions of going on a LA. Things change, you know that.

And again I'll say it one more time there is no way in hell I would have put one dime into any cast iron head if I would have known I could have had aluminum heads with the bigger valve and springs and whole nine yards sent to my door for $820! This is all brand new price point for something like this...
I won't even start the conversation of all the beneficials of aluminum....
Like you said three years ago this wasn't an option for me... Or at least not one I knew about...
