I am running the 4 layer mls HG and i am pushing coolant at high boost
, you need a special surface on your head and block for the ls, now all the reading i have done on the copper titan one, you just throw it on, that HG has orings built into it for each chamber as u can see, so that is the HG i am putting on in the spring. I did alot of homework on that titan HG
