Aluminum slant block

I also made a 3D model of a sleeve that had an interlocking deck that you could send to Darton and have made as a Plan B. But can you actually picture a Slant 6 person throwing down $150+ per sleeve and then paying to have them installed....?LOL Anyway, that just makes the block strong enough to make the next weakest link vulnerable....
Given the cost of used intakes & headers, that's not a bad deal at all, but agreed....what will break next..
