I am not sure about clearance under the covers for the rockers, you may just have to try them to see. You will likely have problems with the alternator. When I put Vortec heads on my '70, I could not use the original slotted adjustment arm that came on the truck. I used one off a '72 parts truck that I had, and it was longer, allowing for more outward adjustment of the alternator.
