thx man i was gonna go with some double humps at first but then decided to go with afr cause some peeps told me that double humps wasnt a good as afr so ya know the rest

 

Yeah AFRs are lightyears ahead of the 'ol fuelies. Id consider some AFRs or maybe Brodix, they make decent large-port heads, although the AFRs probably outflow them.

 

ProTopline 220 or 200

Check there numbers compared to AFR, and is half the cost.
