After
a long wait the TFS HI PORT head is back. The basic head design
is still the same, but has an updated casting with higher
flowing ports in our Stage 1 and Stage 2 heads. They now come
standard with the J 302 style header pattern, so no adapter
plate need for a large header. We suggest these heads for
engines over 331 cid. They do not perform well on stock 302
engines unless coupled with a power adder or high rpm (7000
or higher). The TFS HI PORT is a great all around cylinder
head we use on anything from a 485hp 351 engine to a 1600hp
supercharged/turbo engine. Also, due to recent port developments
we have made over 750hp on motor alone with our Stage 3 head
and RACE version heads on 351 stroker engines. NMRA Drag Radial
record holder and multiple event winner Chris Little uses
our Stage 3 version.
