Headers for a350 Votec

I recommend you get full length headers, they offer the most exhaust flow improvement.
There are many for these cars, cheap steel to stainless, small to big tubes.

The vortec 350 doesn't require different headers than any other small block. The intake is a bit different, but exhaust is the same.
I agree with going full length.
I've heard good things about Hedman Elite series headers. Good fitment, quality and reasonably priced. But I have no personal experience.
I personally have put Dougs ceramic coated headers on my big block Chevelle and I have helped friends put Dougs on a big block 1970 Plymouth 'Cuda and on a 1968 455 Pontiac Firebird. They are a bit pricey compared to most but none of these installs required "performance dents" to get them to fit properly, which is very important if you get ceramic coating. Quality and fitment is top notch.
I have Hookers on my small block Monte and would not recommend them. Drivers side hangs too low and the bends are poorly designed. I can't get a plug wrench (or any wrench) on #6 to tighten it properly and I couldn't get a box wrench on several standard header bolts so I couldn't tighten them down. An open end wrench wouldn't seat so the heads rounded. I ended up buying ARP 12 point bolts with the small 5/16" head just so I could get a box wrench on to tighten them. They were on the car when I bought it (of course the header gaskets were leaking) and they won't go back on if I ever take them off.
