Since no one else has tossed out a recommendation: https://www.lunatipower.com/voodoo-retro-fit-hydraulic-roller-cam-chrysler-361-440-262-270.html

I only checked Comp's and Lunati's offerings. Not many shelf offerings timid enough for a low compression motor with a 2.76 gear in a roller.

You'll most certainly need springs as well. I would bet 440 Source offers their head with springs for a roller cam. Give them a call and see what is involved in swapping hardware.
