Providence:
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.
Most dual downdraft intake manifolds fit.
Most single downdraft do not fit.
Updraft manifolds do not fit.
