which header
I have a 95 f150 351, I was looking at Pacesetter's ceramic coated 72C2223 long tubes which have 1 5/8 primaries and 3/8 flange and the Flowtech ceramic coated 32504FLT long tubes with 1 1/2 primaries and 5/16 flange. Now I now the thicker the flange the better the seal you will get but I was wondering if the primaries are too big for a stock motor, I dont want to loose my scavaging and velocity. I was wondering if any one would have any expieriance with this. I appreciate all the help

I do belive those headers will work fine for your application, i have 15/8 primaries on my headers too, i messed up going with shorties, but still got a small gain, that i noticed, i also have a k&n intake too, along with a new exhaust so all together the headers worked rather well in my opinion.
i also have the 5.8l by the way.
Edit: scavenging comes from one side of the motor to the other side. Helping "pull" exhaust gasses out of the chamber and allowing more fresh air in. This happens by either having a y pipe where both lead pipes connect into one bigger pipe or by having an x pipe or h pipe also knows as a balancer pipe. While i have never used a balancer pipe on my exhausts, i have heard that it can be benificial, and if your having an exhaust shop do your exhaust, they usually include a balancer pipe in the quote.
