Header Question

Thanks for looking.

I'm trying to deciede weither or not to use my pro part 1 7/8 primary headers on my 70 dart 440. The motor makes around 700 horse and these headers work, but it looks like a major pain in the butt to change plugs. I am thinking of going with hooker 5215 fenderwells with 2 inch primaries. I am thinking that would give me more power, but I dont know how well they fit and it there would be any advantage when it comes to changing spark plugs.

If anyone has used these and can speak to the question that would be great. That or if you have any other suggestions as to headers that would be great. I dont mind spending some money if they fit well and would make it easier on race day. I just dont want to plop down 1000 on headers.

Thanks!
