Give them a call and ask what they have first

i want to bore the motor and put the marine pistons in the block can i just get the marine 5.9 kit or what would i have to do?:tu:

you would have to have the block bored to the size piston you are going to run. Then buy the pistons and rings.

ok but can i buy a marine 5.9 rebuild kit

all you need are the pistons and rings.

head gasket to right?

You can use either the .020 over marine or the stocker the only difrference will be a slight drop in compression and you will need thinner injector washers for the .020 over gasket
