Thanks everyone for the great feedback. I am actually suprised that so many of you said "...do the 1-7/8"...!!!", but real world feedback is what matters.
My budget is already stretched on this project, so I may actually hold off on the TTI purchase, run another season with my new stroker but old LA headers (1-5/8"), and then move to the 1-7/8" pipes...the benefit would be that I should actually be able to roughly tell the difference between these sizes (disregarding the hit for the port miss-match between the LA and W2).
How many rpms do you turn.. I ran a 1 3/4 set on my w-2
and it wasnt bad.. I was turning 7800 rpms.. I cant say
if there was any power loss but the time slip didnt see it
but the conditions might have been different(I dont remember)
