I spray them with copper coat and use them. Yes you need to take them apart to clean them properly I cleaned mine thoroughly but never use copper coat. I think you will be happier with the Cometics.

You drill out a rivet, not like its complicated. I would NEVER reuse thme without cleaning them. Only way to clean them properly is to drill out the rivet and separate them to clean them. Maybe its the difference between compression ratios above 15-1 but I have NEVER had an issue taking them apart and cleaning them, then using copper coat on the outer layers. I've never used a Mr Gasket or anyone else's MLS gasket except Cometic. But they will tell you to either NOT reuse them or to wipe em off and never use anything.

Heck I had to drill out 3 rivots and cut part of the gasket on my Keith Black block and B1 head combo. No big deal. The rivets wouldn't let my head seat properly.

Yeah the rivets on the Cometics get in the way of MOST Mopar heads. I have none on any B1 stuff or the Predators.

... I'm not sure that those Mr. Gasket MLS head gaskets actually sealed properly. I can't put my finger on it, but I think it's because they both looked kind of wet (coolant seepage?), which didn't seem normal to me. Additional evidence that the Mr G. MLS gaskets weren't sealing properly: Half of the cylinders have corrosion in the bores where the moisture collected above the ring lands on the outside walls while the pistons remained in the same position for weeks after the dyno session. NOT impressed.

I just use new gaskets whenever I pull the heads off. Easier that way.... I've never re-used a head gasket before. The Mr. G's were new and they simply didn't seal properly. I may consider some new Cometics, or save my money and use one of my remaining sets of the discontinued orange DG gaskets I mentioned previously. The only real issue I had w/ those is they're a big PITA to clean off the heads & block when disassembled... but they sure as He11 didn't leak.

""Only way to clean them properly is to drill out the rivet and separate them to clean them.""
When doing this, I am assuming that you have to reassemble them on the same head and in the same order? Is this correct?
Thanks!

I bought a set of Mr Gasket mls gaskets from Jegs once and they came in a Cometic package cardboard insert, with a Mr Gasket sticker on them, that must of been their once upon a time american supplier before they went with wang chung gasket company.
