350 Spark Plug Heat Shields

I'm putting in a new crate 350 in my 1978 K20. I was going to switch over the original spark plug heat shields from the old motor onto the new crate but one of the four is too badly damaged to reuse.
1. How important are they? Someone told me new spark plug wires are better and the heat shields are less important. Not sure that sounds right... Anyone run engines without them? I have the original cast iron exhaust headers.
2. The heat shields are also very hard to install since the exhaust manifolds are in the way. I have seen some people that have "two piece" ones that would be way easier. They look like JEGS Part Number: 759-DESPB12 but Jegs said they wouldn't fit my Gen 1 350. Thoughts? Thanks! -Will
