Headgasket for I6

[Oshkosh1]

What's the best headgasket available for my Inline 6?

There is a marine mechanic locally with an original Merc gasket for it...it's new, old stock. Get this, or is there a newer, stronger version?

This being an opinion question I'll offer mine. Merc makes some pretty good stuff and most hold up. There are some higher end gaskets but for an inline 6 I don't see the extra cost being needed. If the head and block are stright and flat it should last a very long time. Gaskets that fail most the time happen because of lack of maintenence.

Personally, I have always used Fel-Pro where ever possible, but not finding a marine head gasket from them for your engine. Probably would be OK to use a standard gasket on your engine, since (I think) your not in salt water.


The Merc labeled gaskets would be fine too.
FWIW, I'm about 99% sure Mercury Marine probably sourced them from an outside manufacturer, so you may be able to find a cheaper set for your engine if you drop the middle man.

THIS is the same gasket...

I know it's "old"...but it seems to be of good quality. It has "GM" embossed in it also.
