I just picked up my head after having it resurfaced, the machinist told me it had been done before so now it has had 20 thousands removed from the factory head surface in total.

The problem is I've already bought a head gasket set from cummins with the 10 thousands head gasket. Should I be worried that the exhaust valve will hit the piston?

Also is it normal for the piston to protrude from the top of the block about the thickness of the the old (compressed) head gasket when the engine is at top dead center?

Thanks

 

well you should really have a .20 over gasket cause it is a zero clearance motor

 

i like the .020 marine cummins brand gasket.

 

ok first of all run a .20 gasket to be safe

and second of all (not to pick on you tony) but there is NO sutch thing as a "marine" gasket if you walk into a marine cummins dealer and ask for a stock .10 over and .20 over head gaskets then go to a normal cummins dealer and ask for the same thing you will get the same gaskets! Cummins marine 5.9L takes a stock HG from the factory the same as every other 5.9L. Where "marine" gasket came from IDK but there all the same when I was first getting into this I walked into my local cummins dealer and asked for a cummins "marine" .20 over gasket and all 3 parts people looked at me like I was nuts they all informed me of what I have just said above I did not believe it there was a big deal about over on DTR a few years back after I posted this up and sure enough what those parts guys told me was true. Just a little cummins history lesson I guess.

here to help the point

call Cummins and have them run that part number 3283339

They will tell you that is a "Automotive gasket"

 

I was afraid you would say that, It means my truck and shop will be down for another 1-2 weeks

I've got a question for you BBD, I'm using a '93 block and head in my '96 ram and on the link you just posted, the gasket is listed as a '94-'98 head gasket, I was under the impression that all 12v blocks are the same, (at least as far as the head gasket surface is concerned) is that not true?

Thanks

I managed to get one at my local cummins dealer it should be here tomorrow, I just hope all 12v head gaskets are the same

 

All 12v gaskets will work the same in the futer let me know i have about 20 on stock

a normal cummins 5.9 gasket is not the same as a cummins marine gasket.
