ALL PONTIAC/TIGER RACE READY TIGER CYLINDER HEADS,(Pair) ALL-TIGFA *DISCONTINUED*

The new Tiger heads from ALLPONTIAC.COM feature 400+ cfm flow out of the box. Available in std./stock location exhaust port and raised exhaust port versions, these heads were designed primarily for use on the IA II cast iron block and the IA II/Butler Performance aluminum aftermarket blocks. Available bare w/guides and seats or fully assembled and ready to bolt on with Manley components and a Jesel shaft rocker system. For the race guys there is a fully CNC ported version by CHECKERED FLAG MACHINE.
