Tough to find; I recently bought a "conversion" gasket set that had everything but the top end, from eBay.

Someone had posted about a place that would make you a set but that's all I recall.

Cometic can make custom gaskets. Also gasketstogo.com can do custom MLS (multi layer steel) gaskets whereas Cometic will not do one offs or small batches of MLS gaskets.

You can make head gaskets out of 16 gauge copper sheet. I do it all the time for antique engines. Gmc v6 used copper on the early motors. And it's all I use on the ones I redo.

http://www.gasketstogo.com custom makes gaskets in any material and and configuration. I have used them for VW diesel engines with great success (as well as loads of early vw diesel & rabbit/caddy pickup truck owners) & am also using them for some custom big bore Suzuki GS 4 cyl motorcycle multi-layer steel head gaskets.

On the MLS gaskets at least, there is a big price break when purchasing 5 or more gaskets, due to tooling/setup involved.

What tooling do you use and how do you cut the copper sheet?

Is that for a 305 or 351? I would assume that most everything crosses over between the two except the head gasket, correct?

the set was for 351s and 401s

All but the magnum top end gaskets should fit the 305
