So you have to make sure they’re for an Oldsmobile 350 engine
Most likely any header from a small block Oldsmobile car should fit in
A c10

Yes a ford roller rocker will fit the 350
For a mild engine I recommend comp cams magnum
1441-kit roller rocker kit for small block olds, available at jegs

Thanks for the info! Yea I'm keeping mine fairly mild. Will hopefully be looking into an overhaul by next fall with a new set of speed pro pistons which will bring me up to 9.5:1 CR with my current #8 smog heads. Looking towards a Comp Cams "Thump'r" grind or something similar in the Lunati Voodoo cams.

If it wouldn't cost me as much as it did for you to build the engine to ship it up here to Canada i would seriously think about it lol. That said...I may idly look for a 455 to drop in place of my 350 and drop the 350 into my '69 now that i know what mounts would be needed. Granted i will need to get some of the frame mounts themselves from a 73-87 C10 to convert to the newer clamshell mount. Though at the same time i kinda wonder what it would take to drop an Olds into a GMT400 chassis. Im in the process of buying an old rat rod i had once owned back. Except that in the years since i had it the body has been swapped to a '93 C1500 chassis to gain modern suspension and braking.
