Why do I keep blowing head gaskets?

RockinRobin said

Gen 3 hemi aluminum heads. About once a year I get a water leak and have to replace a head gasket. Motor never runs above 190 water temp. I've been using Fel Pro. I get the heads surfaced every time they come off to make sure they are flat. Compression ratio is 13.5:1. Should I use a thicker gasket than stock since I've had the heads surfaced more than once? Standard thickness is .027 but Cometic has many thicknesses available If you can find them.

I don't know if you use copper coat but I would use 10 coats on each side.
I think the bolt spacing has a little to do with it.
I do a lot of cylinder head resurfacing, 3rd gen hemi heads are pretty rare to see..
You could try a thicker gasket if you want, it's not necessary though.
And o-ring the head.
I use copper coat on my head gaskets.
The surfacer at my work had a 24 grit cutter.
It made a little less than desirable ra finish so I felt it would be a good idea. Has not leaked
