AFR 185's CNC TFS TW
Int=2.02 Int=2.02
Exh=1.60 Exh=1.60
Int.Ports=185cc Int.Ports=185cc
Exh.Ports=69cc Exh.Ports=66cc
Combustion chamber=61cc Combustion chamber=65cc
Both are CnC'd, the AFRs are cheaper by about $500, Both need special pistons, TFSs have a better chamber design and different valve locations.
My views: Bigger Combustion chamber = ability to have a lower CR
