60lbs springs
 

we are selling new low swirl heads with 60lbs springs installed on exhaust.

these heads are not suitable for California law.

What do you mean by low swirl and how is that accomplished?

low swirl is how the factory cuts the intake ports on the head, these heads are used on equipment, like backhoes, grinders, etc.
they have the 60 lbs springs installed on the exhaust port and the intake are cut with a low swirl.

they also are supposed to be able to handle heat better.

there is also the 12v oil pump that is for high out put, it has extra holes in it for more flow.

alot of people think the marine is the better way to, it is the construction side of cummins that has all the good stuff

How much
