Our 1/2" thick flat 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 is easier and welding is hidden for a nice clean install.
The corners are nicely rounded.
Each exhaust hole is CNC chamfered on the back side 
designed 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.

In the early 1960's a gentleman in Washington State was playing around with a couple Model A intake manifolds trying to see if he could make an exhaust header. He ended up making a pair of castings that worked and looked neat.  
C. Yapp bought his patterns but found that they needed modernizing.
New modern casting tooling was developed.

 They look "steampunk".
Sound is deep, mellow and leaves no doubt
that you have the power.

 The cast iron Split-Y headers give a smooth deeper rumble.  
Believe me, nothing in the hobby sounds or looks so good.
They're good for 5 HP increase to boot.
All hardware is included. 
Shown here are the flanges, gaskets and nut/bolt/washers.
These 2 steel flanges are used to weld your collector pipes to.
Shown are set of 4 gland rings for port alignment, header to block bolts and special over sized washers. Instructions included.
Fits Model B and A engines.
Filter side plates and B fuel pumps can not be used.
