Reply to "Brodix Alum Heads"

They've been in my 351C aluminum heads database for years. The BF300
series Brodix heads are C302B replacement heads. Don't confuse them with
the BF200 series which are Yates competitors. When they first came out
there was a rumour they were going to offer a pre-ported version but it
never materialized. Also, they were orignally offered in a rockershaft
only version but Kelly Coffield bought a set that were set-up for stud
mount 351C rockers.

Brodix BF300 and BF301 Heads
----------------------------

The Brodix BF300 is a replacement head for the popular Ford Motorsport C302B
race head which is no longer produced. According to Brodix, the BF300 series
heads use "all existing hardware from previous canted valve Ford heads" and
should be a bolt on for those running C302, B351, or A3 heads. Brodix lists
two rockershaft systems for the BF300 series (Jesel KRA 02211 and T & D 7200
or 7201). There is apparently a version that will accept 351C roller rocker
arms. Cant angles are listed as 9.5 degrees x 4 degrees on the intake valve
and 9.5 degrees x 3 degrees on the exhaust valve. Standard valve sizes are
2.125" intake and 1.600" exhaust. Pre-Yates Ford Motorsport and Edelbrock
high port intakes should work. Seats are ductile iron (compatible with
unleaded fuel) and guides are phosphorous bronze. The BF301 has Nascar part
number 3941078.
