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.

 To fit Model A, B, Burtz engines built with "F" head OHV conversions like Riley, Roof and many more era conversions, where the exhaust ports are in the block and
the unused intake ports need to be covered.

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 leave 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 2" 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 oversized washers.
Instructions included.
Fits Model B and A Ford style engines.
