FS: 4AG 16V/20V Universal Exhaust Manifold Flanges
Laser cut from 12mm mild steel with a universal design to fit all 4AG motors (Bigport, Smallport and 20V).
However due to an error in the CAD drawing, the right most slotted bolt hole is too long and hits the coolant pipe on the head of a 20V motor. This is not an issue with 16V but can easily be fixed with a grinder to make it work with a 20V (see pictures, green line).
$50 shipped anywhere in Australia $40 + P&P, currently listed on eBay -

Flange bolted to a Smallport head
This is where it fouls on the 20V. Basically cut along the green line with a grinder and the flange will work properly on the 20V as it was suppose to.
