|I complete almost all of the assembly of the motors and then paint
them overall aluminum with the SNJ Metal spray before
contrasing colors. I also install the headers. The diagram below
shos what I do.
One note is that the preinstallation of the headers can be tricky. I
first install the right side headers as they rest against the trans
and this palces them in the proper position. I use soperglue to do
this to instantly set them. I then glue the left side headers in place
with tube glue to allow me time to properly space and position
them. I use the exhausts as a guide to do this. With the right side
fixed this is easy to do. I hold everything in place. (Takes a little
practice.) I then iht the left sde header joints with a drop of super
glue and activator and it is done. Assembly goes quick.
