450 lp head

M1 · Jan 5, 2016

Going to put a 450lp head on my M being it don't have the breather pipe on the back of the head do I need to put a breather pipe in my valve cover.

It is a good idea. A restrictor to a hole about 7/32 with a hose connected to the aircleaner as before would do. I think a short pipe that fit inside with shredded brass filler would help keep liquid from going directly into the intake. DO some later farmall valve covers have the fitting?? Seems to me, but do not remember. Jim

Yep when I put a 400 gas head on my aunts M, I used the 400 valve cover as well. It already has the fitting/elbow for the breather pipe in it.
