1.625" primary tube 3/4 length headers work well for clearance but many feel the tube size restricts a >400ci built/non-stock engine. A 427 SBC (or even some fairly aggressive 383's) would def benefit w/some 1.75" primary tube headers of similar construction but for some reason they aren't made.
There is an argument to be made either way as far as how much is 'lost' using one over the other. Ultimately, it boils down to the combo & the end users wants.
Your RWTQ/HP numbers are nice for sure though!

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....
Cubic inches is like Indiana Jones with a cheap pistol.
