Trickflow 225 "High Port" Cylinder Heads
ZSR prepped custom Trickflow 225 High Port Cylinder Heads. These heads have MANY different options that we can do to them and if you need something unlisted, just email or call us. We can do receiver grooves in the heads for O-Rings, soft chambers, etc.
These heads work great on N/A and power-adder applications. Very thick decks allow them to stay flat under extreme boost or nitrous. The TFS High Ports are some of the best 20 degree heads on the market.
