(Please use the GIF chart below along with the following description.) \"A\" dimension, right angle to the exhaust port flange of the head, is 5.25\". \"B\" dimension is in 2 measurements: from the centerline of the bolt holes UP = 4.5\"; and from the centerline of the bolt holes DOWN = 4\".
Note: One end bolt hole is slotted to the end of the casting. This will allow the installer to start one bolt into the engine to hold the gasket, and then slip the manifold onto that bolt and use that to support the manifold/gasket to make alignment and insertion of the other bolts much easier.

Installation Tips
To help determine fit:
"A" dimension, right angle to the exhaust port flange of the head, is 5.25".
"B" dimension is in 2 measurements: from the centerline of the bolt
holes UP; and from the centerline of the bolt holes DOWN.
The UP dimension is 4.5", the DOWN dimension is 4".Overall length from front-to-back is 18.5"One end bolt hole is slotted to the end of the casting. This will allow
the installer to start one bolt into the engine to hold the gasket, and
then slip the manifold onto that bolt and use that to support the
manifold/gasket to make alignment and insertion of the other bolts much easier.The ports are just under 1.375" square. There is enough material around
the ports to open them up to 1.5" or more, should the customer wish to do so.
The 2-bolt flanges for beginning the head pipe installation are sized
for 2" tubing. They appear to be a fairly normal flange type, and could
be opened up to 2.25" or more if the customer so desires.
The outlet port of the manifold is bored to 2" ID.
The collector is centered between the center ports on the head.
