Exhaust header Gasket

Metal clad one piece. Can be cut in sections for intake manifold seal. Photo is of metal front (silver) and back side (grey).
 Temp out of stock
 Both sizes: 4 or 6 hole

Only from Scalded Dog Speed Parts: Our 1/2" thick plates are special.
The back side has a chamfer machined into the exhaust port holes.
Your welder inserts the 1-1/2" dia. steel tube into the hole, flush with the backside and welds into the chamfer. The finished job will not show welding for a nice clean install.
4 hole version is for welding a header to fit an engine built up with an "F" head type OHV conversion like the Rileys, Roofs and many more era conversions, where the exhaust ports are in the block and the unused intake ports need to be covered.
Each exhaust hole is CNC chamfered on the back side to receive weld for a clean front side look.  Holes are 1.5" Dia. and plate is cut from 1/2" thick steel stock.
Fits Model A and B Fords. Depending on final application these may require longer mount studs or bolts.

Fits all Model B and A engines.
INCLUDES: Two Iron "Y" castings, 4 gland rings, 2 weldable header flange plates, hardware,  lower gaskets and full Instructions.
Deep mellow tone.
Not loud and tinny like tube headers.
These can be fed into one pipe or fed back as two functional pipes. Castings are fine grained best EXHAUST quality and take coatings nicely.

Providence: A gentleman in Washington State was playing around with a couple Model A intake manifolds trying to see if he could make a header using the mount feet and the legs of the intake. One thing turned to another and he ended up making a set casting patterns from old parts that worked and looked neat, this was in the early 1960's.  I bought the patterns in 2005 and they sat around for a while. Basically they were too heavy and a bit rough.

Bill Smith, of Speedway Motors stopped by my office, he had a way of sniffing out speed parts, and told me they were too heavy and needed a redo on the tooling.  So new tooling was made so that each set of Split-Y headers are stronger, lighter and better braced for long service along with a fine surface quality.  Not only do they look "steam punk" based on old parts . .they sound so deep and mellow. The sound leaves no doubt that you have the power, but the those harsh high treble tin pipe notes are gone . . just a smooth rumble.  Believe me, nothing in the hobby sounds so good. These headers are the originals and they're good for 5 HP increase to boot.
All hardware is included.
