Magnum heads worth the effort?

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...
yes, the procomps are a good deal when they have their sales. But to buy and bolt on I couldn't..... :( ….. I would have to question the quality of the springs, valves, are they sealing, ya know. Even on sale, I'd be well over a grand when I was done
