Anyone know of a Big block composition head gasket that is about .045 Thick? I can find MLS gaskets that thick, but my short block is already together and it wasn't decked for MLS gaskets. I thought ROL used to make some but can find any info on them anymore.
The only Carbs I care about are under the hood!

I can find .051 head gaskets, but would like to keep my quench height around .040.

RB stroker with the normal D-Dish pistons. Piston Height ranges from zero to .005 above deck with the piston rocked to the highest reading as close to the centerline of the piston as I could get with these style pistons. Figured I would stay on the safe side with alittle more clearance then the Normal .039 gaskets.

Sadly ROL is SOL, or maybe more accurately DOA.
If I remember correctly they were bought out and killed off.

running up my post count some more .

Use the MLS gaskets and copper coat them. The copper coat will make up for any imperfections in the deck. Gee, I wonder why the guys that make those gaskets won't tell you that ? They are very adamant that you NOT use their gaskets on the wrong surface !!!

I know the old orange Detroit Gasket composition head gaskets I've used measured about .042" compressed, even though they're spec'd at .038".

They are very adamant that you NOT use their gaskets on the wrong surface !!! Of course they do. I've used them on meticulously machined and prepped surface and they have leaked coolant before so I don't risk it.

I thought ROL used to make some but can find any info on them anymore. You say it wasn't decked for MLS gaskets. Have you put a profilometer on the deck surface? What was the RA?
