Description

PN: TEA-250HPTF-CUSTOM
1963-1995 Ford Windsor Small Block
Mechanical Roller Lifters

Designed for drag racing or limited street use these heads offer excellent power gains due to their unque design. The High Port® 250 heads feature 250cc intake runners and 70cc CNC-profiled combustion chambers. This design is based on our 255 head but the chamber and intake runner have been redesigned for use with a stainless intake valve. It is intended for 4.125″+ bore engines, this 20 degree inline head optimizes mid lift flow and maintains it up to .900″ lift by utilizing a custom 50 degree 4 angle valve job and modified 2.125″ stainless steel intake valve.
Optional milling available.
Flow sheet provided for your heads.
