Been over thirty years..so have to ask. Do header gaskets go on dry now. If I remember, we used to spray them with something. Is that still the norm? If so, what is used?

I think that was a copper spray. However if the surfaces are flat, the gasket will seal fine, bolts need to be secured evenly.

To much goop unnecessarily used ...... IMO

Having tried just about everything on the market, I can say that the best available today are Remflex. Just pay attention to the bolt torque - overtorquing will crush the gasket and mess it up.

I agree with Joe, Remflex are working great for me. I torqued them in three steps which may have been overkill and used locking header bolts. I have an old set of hookers that tended to blow out other gaskets.

Just use Remflex, or all metal copper, or alumunim gaskets.

Makes life simpler for a few addirioal dollars.

I quit using header gaskets. I bought a set of Sanderson headers for the roadster. The instructions said not to use a gasket. Instead put a 1/8" bead of high temp red silicone around the ports on the head and let it sit overnight and cure. Then install the headers. It worked great on the roadster.
I had built a set of headers for the model t coupe and always had trouble getting them to not leak with gaskets. So I tried the Sanderson method. After putting the 1/8" bead on the heads and letting it cure, I put a very thin coating of silicone on the header flanges and installed the headers, I finally had sealed headers.
It's a lot cheaper than gaskets. You might give it a try.

I have been using Fel Pro gaskets with a steel core for 20+ years now. Never had a leak with any of them. Nor have I had a header bolt come loose.

For a small block Chevy with stock port sizes, P/N #1444 is ingrained in my brain!

55s & 327 were a popular build in high school, and the 301.

Same here, my favorite header gasket set, a metal and gasket sandwich.

Good seal never had a header bolt back out. Prefer allens, for a cleaner machine appearance
