Header Input Needed

ok, i am going to throw this one out there and see how many bites i get, and i am hoping to get a bunch. i have talked to several people on this one, and have recieved 2 different answers. we run 540" hemi with dart fuel heads, 14-71 hi-helix ssi blower in an altered. 12 to 1 comp. blower makes about 43# at 8600 rpm. the heads have 2.375/2.000 valves in them. my question is: WHAT SIZE HEADERS DO I NEED FOR THIS MOTOR? the people that i have talked to say either 2 3/8 or 2 1/2. any input would be greatly appreciated. i plan on building a set of zoomies within the next month, and need to order the bends.
thanks darren

 

Darren,
Post or send me your emaill address in a PM and I can send a DOS program called PipeMax. Enter your specs for your engine and it will calculate header size.
