the only difference I saw between the felpro & the cummins was in the part# marked on on the gasket.It is the same# exceptwith FP in it. I just replaced mine last month thats what I found,I had to replace it because someone previously replaced it with a "cummins" gasket but should of resurfaced it. All better now

 

cummins brand .020 over marine head gasket part number (3283339) is different than a felpro around here.

 

Just compared felpro to cummins gasket in a guys shop. I wouldn't run one, the metal fire ring is alot smaller than the cummins. On a stock motor that isn't getting beat they might be alright but I would never run one after looking at them. Use the cummins gasket.

 

I don't know about Felpro but there is other aftermarket companies that make them exactly the same and haven't had any problems

 

Go to youtube and look up thedieselstops channel he will show you the difference between the 2 gaskets.

 

I am going to go with Mahl hs4068. Are they any good?

 

i dont know. vannest performance always uses cummins brand. they may be others that are just as good.

 

I'd use a Cummins
