try schumacher headers i have them on my 440 they are block hugger tri y work good cost effective and do not capture the starter. Plus you get to run the exhaust under the car
I may have some still at the farm near chatham ill look and let you know. i live in halton area so its pretty close to you 100.00 for 4 if you are intrested and I still have them they are 4 inch pattern off a 70 dart.
i built a 440 stroker for my dart parts from 440 source 2300 shipped to can now its a 512 cid 6500 to put it all together not bad for a stroker on a budget lol
