I have a 99 Dodge Cummins with twin turbos /water meth/big injectors/race fuel pump and I am blowing head gaskets !Oh yeah ,after the first use of my water meth I blew the head gasket.I sent out my head to get it decked and o-ringed and we put in ARP studs.We followed all the directions in torquing the head down and just recently blew the new gasket out (approx.900 miles).It was a stock cummins gasket.
I'm looking at the difference or pros and cons of a mls gasket verse a marine gasket .Is there a difference ?
What can I do to solve this problem ?
Is there a better gasket or product out there?
HELP ?
