Mild 360 Magnum Build

It does seem a bit hard to get any aluminum for production. Waves of havoc left over from trade wars?
WTH?!?!
I'm not going to get into my thoughts on trade wars but why start a war you can't win....the shop sells a ton of pro-max heads and even those are months out...plus I have been privy to at least a dozen small block builds and the numbers they dyno at with pro-max heads...so would like to do a trick flow build to compare...
