The 781's will work fine.
I would install a set of 2.19/1.88 do a good valve job,bowl blend, gasket match.Is this a street car or a drag car?If it is a drag car then I would look into a victor jr. intake.If it is a street car then your intake would work better because it will make torque at a lower rpm.
