W5 heads

This was not B engine head. Just a small block prototype/iteration. I have small black W-2 1/2 flow charts too.

Just stuff Tom Hoover's group came up with for it's developmental contactors to create or enhance.

Sorry if this is taking this discussion off topic. I just wanted to point out there's been SB with even larger than 2.15" intakes.
I think their are some versions of the W8 and W9 that use 2.19" intake valves. But 2.125" is pretty big for a head with the valves in the stock location.
