Howdy Y'all, I am looking for infomation regarding the current maker of the Jern or Hansen-French adaptor plates for a Chevy Two port head conversion. I have found a couple of these heads for sale and even an olds three port but never pull the trigger as I'm so new to this hobby I don't know the "In the know" knowledge on how to contact the people I need, heck sometimes I wonder if I'm too late and that knowledge has been lost or worse the maker has gone to meet the maker. Dark I know but so is the knowledge I seek, hahaha.

Anyways, If anyone has info related to the Jern or Hansen-French adaptor, or even a new adaptor please let me know. I'm sure others would like this info as well.

Keep plugging away at your search, eventually one with pop up. The same adapter would be used with the 1,2 or 3 port heads. The other thing that you need to find or make, the water outlet piece. It mounts to front of the head where the Chevrolet outlet went and mates to the head adapter.
If you do find a Thunderbolt adapter, Olson Gaskets should have the pattern for the head gasket, think it is the one that goes between the head and the adapter, the other one can be bought at Lang's and others.
