What`s more likely to blow out, a metal reinforced gasket or some RTV?
Personally I wouldn`t trust just RTV. I do gasket and RTV

That’s the way I’ve always done it.

Always used the high temp red rtv on the manifold gasket side. Dry head side. No leaks. When you remove the manifolds the gasket stays with manifold. No mess to clean on the head side.

No gasket nothing to blow/burn out. Silicon ain't goin' nowhere.

I went with just a 3-layer metal gasket (and used a torque wrench), but haven't started it yet. Everything cleaned up well and flat-edge looked good. We'll see what happens.

BTW- If your running WB02, might wanna remove the sensors from the area when using RTV. Back when I was active tuning cars using WB-02, the sensors would experience "silicone poisoning". Symptoms would be lazy response at first, then slowly die. I would remove them and place in a zip-lock until the RTV had thoroughly dried and I was ready to re-install. Don't know if the WB02 sensors have changed since then (early 90's) but thought I'd mention it.

If surface is somewhat flat and doesn't have imperfections I use Mr gasket Ultra seal gaskets, I put a slight amount of antiseize on one side so they will separate without tearing/ On my dyno my favorite set of BBC headers I used mr gasket ultra seals with slight amount of hi temp rtv between header and gasket and tiny bbit antiseize on cylinder head side so gasket doesn't bond to paint if customer brings a engine to be dynoed with fresh paint.
Personally I hate when someone just uses RTV and its smeared all over, into every nook and cranny, looks like a cobbled mess. Theres quite a few things too where exhaust doesnt go straight on too, you have to work it in, Id much rather slide a gasket in at that point on front/rear bolts then smear a bunch of RTV down as you work a piece into place, just, my opinion.

I always use the factory, metal and fiber ones. Seems to work the best with cast and aluminum manifolds, without failures. Never used RTV. Manifolds are too hard to get on and off in a couple of my boats. Being glued to the head would be an added nightmare.

Exhausts on watercooled exhausts run so much cooler than their auto counterparts I’m surprised there's a marine exhaust sealing issue with some of you. Or is this just with header peeps ? I’ve never seen an exhaust manifold issue with using just normal felpro exhaust gaskets.
