The factory roller blocks put in trucks almost always have flat tappet cams.
You use the regular SBC timing set, just like would have been used before '88. In '87 they had a one-piece rear seal and no roller cams, so the one piece seal is not of importance here.
Use whatever you want for a timing cover. Your late one would be fine.
For the balancer use whatever you want, these weren't unique to the engine.
Basically all you are doing is just eliminating the cam retainer plate, dropping on a standard timing chain of your choice, and throwing in a good old fashion flat tappet cam. There isn't really much magic going on here, or anything the factory didn't do themselves.
