head pipe HELP!!!!

I have a 1987 250 X with 11:1 Aries Ultra lite Piston, White brothers Pro Meg exhaust, Web all-around cam, air box mods, 20 inch razors on rear. Would a White Brothers head pipe be worth my money? Would I notice any more power? Would this set up be able to pull a 14 tooth front sprocket?

Thanks

Yep , It should have no problem , i used to have one with my stock motor , but then i went up to 22" tires and had to go back to stock gearing.
You can also get a powroll oversized header for $90 that will do the same thing as white brothers header.
