360 mag with X heads anyone?

Thanks for the response, yes I am aware of the magnum head advantage I was already shopping for magnum valve springs when it dawned on my that it had the cast iron intake of an LA motor with the angled bolts. I pulled the VC off to identify the head but unfortunately the casting # wasn’t under the VC. I also just read that there’s oiling differences between LA and magnum so it seems to me it shouldn’t work. I’m perplexed as to what exactly I have. I’ll have to pull the intake off to check casting #’s and know for sure what I’ve got.
