I have run open headers for 2 years on my 85 monte carlo ss, with no problems with anything. No burnt valves and gained power. Ofcourse it was a 360 (350 bored.060 over) with some slight tweaking to it.

And it sounded awesome.

 

Your small block chevy doesn't require a lot of back pressure to create torque. Our v6 does require back pressure or torque will be lost. How it all works I still don't know. Can someone explain why our v6's need back pressure to create torque?

 

It means LOUD! aka Illegal unless your car doesnt have to be smogged no more...

 

I know a v-6 requires more backpressure to create torque i was just statin how its not always that way.

I do understand why this is so and how it all works but dont wanna type a whole story so i will try to find a link to an atricle of how it all works for thos of who you dont completely understand all of this.
