408 Stroker Build Suggestions

see my previous comment on that unknown duration Hughes cam, not questioning the quality
if you run roller tip rockers you have to budget the shaft relocation (if you are going to run any spring and rpm)
i'd run oil through the pushrods lifters and pushrods with either rocker style
1.6 really only help on the intake- and you could shorten up the duration one size but without any head flows and dynamic compression I can't say
on the edlebrock heads you are talking about the wedge closed chamber heads not the open chamber ones- right?
run the manifold and gears you have till you get dialed in- good suggestions on manifold utilization but I'd try no spacer then -4 hole spacer first
I do not like double pumpers on the street- is this a race only build? If you already own the carb then ok
if you do not then run what you have till you get dialed in
