Hey guys, this thread is older than 90 days. Shame on you all. This is a public warning, do not post in threads older than 90 days unless you are the OP
no, I am suggesting taking it to an aluminum fabricator that will cut out the corrosion and weld in new bits of metal, then dress it back.
the issue with your plan is the corrosion will be under the JB weld, as its already in the metal that you hit with a wire brush.
the one issue you will come into. the JB weld will come loose in a few months as the corrosion is into the base metal and will propagate between the aluminum and epoxy
I recommend getting it welded.
This is a pay once cry once type of repair.
Im going off what I pay at FGCI.
in 2019, I paid $16/gallon or $64 for a 5 gallon pail. in 2023, I paid $54/gallon, the 5 gallon pail was ~ $220. its higher today.

Just an FYI, price of resin has more than tripled over the past 5-6 years. what used to be a $16 gallon of boat yard resin is now $54 and that is picking it up and not paying the EPA fee to ship.
Most of the Ford marine cams I found are in the 260 degree, 0.445" lift range
At a minimum, go up in rocker ratio
It may be part of your issue, but not all of it
