Dougs or TTI Headers?

For an early (pre-67) A-Body, I think we all acknowledge that a fenderwell header is the only solution when absolute horsepower is concerned.

I was hoping this thread would compare and contrast the various fitment issues regarding bellhousings, transmissions, starters, linkages and the like. Pictures would have been cool. Aside from the points of friction outlined in Dave's 66 build thread there really is precious little regarding the TTI's and absolutely nothing about the Dougs.

I'll cast my vote once I make the decision what headers I chose to install on my early A, and I evaluate the fitment. This may be months from now.

Anybody running Dougs with a 904 please post your results. Pictures of starter and steering clearance would be nice as well.
