1262 has a smaller port opening than the 1250. If the 1262 was on your car, then get the 1262S3. You want the steel core version, not the plain print o seal gasket. Make sure the surfaces are squeaky clean and dry..

Looks like the alignment on that gasket in post 232 is off, unless it's a trick of the perspective you'll never get both the water ports and air ports to not overhang.

Only rtv you should use doing these is on the front and back rails, a good thick bead along those walls from corner to corner. I use permatex black, but right stuff is really good too. One trick that ive done lately is to spray a little, thin layer of gasket adhesive on the head side of the gaskets, the s3 versions dont have the tabs that notch into the head gaskets, and this keeps them sliding around when installing (which they still can move slightly even with corner guide studs).

cant see the picture- look at the gasket you took off- it should have a part # on it- get the steel version of that gasket. You want the gasket to be at least as big as the ports on the head.

this is backwards, the 1262 is the race-port version of the 1250 (and the 1262r is even bigger )

chuck- correct, typing too fast. 1250's are 1.2 x 2.0 and I think the 1262 are 1.2 x 2.1 . That's why I said for him to look at the ones he took off for the P/N

The right stuff for the win ! And the I use it on the front and rear rails and water jackets . That's just me . Those other gaskets don't look healthy. Change the oil finish the gaskets and see what the deal is

Exactly what I would have posted. You will never use anything else.

The s3 is the one to use, trimming of the 1262 around that water jacket will just make ut fail again imo. It is odd though how it seems the port alignment is off. It needs to go forward just a tad, but then it looks like the gasket will partly cover the water port.

Like i mentioned a couple posts up, the lack of the interlocking tabs is why i spray a thin coat of gasket adhesive. Will let you put the gasket where you want it without putting in a slippery bulge that will make the gasket fail again.

ok...i guess ill use the s3 then,i was just concerned about the outer edge of the water jacket there,the old ones were rounder a bit and had more material,when i read about it before my blower ppl just said to trim it just like the engine builder did...i do want the metal version but all my searches only shows the s3 as the upgrade,guess this is it....these are afr 185 heads by the way
