View Full Version : Pushing coolant... New L19's or ring head
Don't bother with the o-ring either, there is no need and they are a pain in the ass to install correctly.

Head surface RA varies per gasket used and material used. Which gasket style are you going with?
Im not sure yet. I already have the titan HG and would like to use that but am skeptical because of what others have said but then I find people with very good luck at high power. What do you guys think, will the titan hold?
The titan will leak. Copper headgaskets don't work well on a DSM. Resurface the head, torque the ARP's to 100 ft-lbs and use a stock headgasket. If you are really worried about it, use the Felpro gasket. Sell the one you have to someone on Ebay or something. Next time ask here before you buy :D

My Cometic went for some strange reason, no racing or anything, but did make 520ish at DB. Replaced it with another Cometic and the same old ARP's I've had for years, I'm not worried about it.

I run 29-30psi on E85 with a factory internal 2.0l with the Mistu metal headgasket. It doesn't push any coolant now. This donor block did push coolant when it was first put into the car though, as soon as you boosted it, it would overheat and push coolant. It could idle forever with no problems. We tried doing headgaskets and milling the head flat and it would never fix it, until we pulled the whole motor and got the shortblock decked, then all problems were fixed.

I second motors by gosh.
I just put l19's in my new motor I am building along with a fel pro 1153-1 headgasket. I have not ran the engine, so I cannot comment on the gaskets actual performance, but I can tell you this thing is friggin impressive. 5 layers with 3 firing rings per cylinder. The rubber coating is so stickey, just holding the gasket, it sticks to your fingers. The center layer is very thick with the biggest firing ring. Apparentley it was built for Rau? and from what I have researched, it almost indestructable with l19's
The l19's are equally impressive. As I torqued the head down, I was amazed at how much harder I had to pull on the torque wrench compared to standard arps. There is no stretch as you reach the torque, just rock solid.

I have a old cometic HP in my car, held the 36psi on the dyno and 47psi on the street just fine....

Do not over torque the L19s they will break, and use a lot of the molly lube thats for sure.
