Which brand header is the best?

I stand corrected on the /6, like yours my front three go to one and the same with the back three :thumblef:, Looks like your headers would not hit the water pump :cheers:, but the 170/ is 1'' shorter and I think they hit down low somewhere on the block, starter or the chassis
My 360 made better 1/8 mile times with the exhaust hooked up :burnout:
The truck would run a solid 8.30 1/8 some times 8.15, but uncork the headers and it was good to make a 9 second pass.
Thank you for your wisdom on this SS, I may remove my 2'' tail pipe and go 2 1/4'' when I put my new head on :thumblef: I will be picking your brain on a came grind if the day ever comes to take the good head I am running now bone stock.
