Hi everyone.

I am looking to help my pulling WD45.

I was told that a Leroi (226) governor is heavier and would help my WD45 pull stronger.
Any truth to that?

I might have a warped head on one of my tractors. It has A LOT of compression and keeps blowing head gaskets. The same person said the valves in a Leroi (226) head are larger than the Allis, and since the head has a combustion chamber, it would give my 226 more pep.
Any truth to that one?

Thanks.

If you don't change pistons to offset the chambered head,you wont have squat for compression or performance.Your friend ain't as smart as he thinks...can't speak to the gov but my bet is AC all the way.
