December 29, 2025 at 2:13 pm #302748Hello Eric and welcome to the forums!
In case you don’t already know….there is a SIG Group Leader in the club for Champion Hot Rod. You can reach out to him via the contact form on the SIG page here….within the Inner Sanctum.
His name is Cooper Jess

Try doing a refresh on the AOMCI home page and verify you’re still signed in. Sometimes, after inactivity or doing other things on a device, AOMCI will sign me out even if I didn’t delete its tab, so you you might just have to sign in again.

It is possible to cut out gaskets yourself using small scissors, hollow punches and gasket paper. Tubs has an informative video about making gaskets on YouTube. I would get you the link, but my YouTube app has given up. 🤷♂️

A 1955 is 4MM-HR. A 56 is 6MM-HR. Coils are no longer available however by filing down the sides of the coil laments to 7/16 you can use the OMC stile coils as substitutes. Much the same as in this video. https://youtu.be/OxPHe8EPe1Q?si=tjv5MZrSUTP-pJaf

Here is an old video I did on making gaskets. https://youtu.be/I0FrFA__n00?si=CKvPoBlhhQPMey3g I’m sending you the email to Cooper Jess in a PM. He is the man when it comes to these Hot Rods.

December 30, 2025 at 8:29 am #302786On the gaskets I have the material and have been making gaskets for years but was looking for a kit but I guess not available. Coils are rusted swollen fraying no good. So this is were I am at now, I could have rings made but that itself is a big if, would hate to just give up on this project. I am restore a hydro plain t5hat set world speed record in 1972.
