Big Twin Side Valve Head and Base Gaskets soon available from Cometic

This is a quick announcement to the greater community of big old flathead freaks.

I recently contacted Cometic Gaskets to get some higher quality products as I button up a motor and was surprised to learn they did not have base or head gasket patterns for Harley Big Twin Side Valves. I'm not 100% happy with current after market gaskets, so I sent them several NOS gaskets (in copper and fibre) from my collection for CAD conversion.

Long story made short, in about three to four weeks the patterns will be done and tested. I have after market and original 80" SV parts on the shelf; so I'll test the patterns with both to ensure fit. After that, any one should be able to ring them up and order "custom" head or base gaskets in just about any material and thickness you desire. Cometic's website lists all the materials and thicknesses they stock -- as you'll see the combinations are nearly endless depending on what you're doing to your motor and why.

Here is a direct link to that portion of their website:

I'm not 100% sure on the final cost; but they should be in the range of $15-20 per head gasket and $8-12 per base gasket depending on material, plus shipping from Ohio.

So, if you suddenly find yourself needing stroker plates or a special thickness head gasket to help hustle your 80 year old obsolete iron down the road . . . it should be a phone call away.
