You' be ok with 1-3/4" tubes but most would recommend 1-5/8" headers for a 350 that never sees the dark side of 6000 RPM.

Hooker 2130 would be a better choice, 1.62" OD X 30" long.

What is the size of your exhaust ports, doesn't make sense to go much bigger than that or the velocity will suffer in more ways than one.
