From Yestertech World Headquarters
(Home of SR-56 Blackbird)
Now available - Yestertech Headers
- Fits ‘54-’56 Ford & Mercury, ‘57 and others soon
- FLOOR SHIFT REQUIRED!
- Dual Exhaust Equalizer required
- Automatics may retain column shift with some modifications
- Mandrel Bent 16 gauge, 1.625” OD primaries
- Choice of 2.25” or 2.5” collectors
- Laser Cut .25” Thick Flanges, any thicker adds weight penalty
- Flange surface that contacts head has flat ridge, eliminating need for a gasket
- The 1.625” primaries are not equal length, but a header with a minimum number of bends also has advantages
- Primaries are paired in a Tri-Y configuration for best scavenging torque and minimum loss of that great Y-Block Sound!
These headers are much superior to other Y-Block headers on the market
