I see your 318 has the 3 spider bosses and the taller lifter bores for the roller cam.
Good deal now all you need to find is a long snout roller cam (stock 360 roller cam is an option too, with a little more lift and duration than stock if the aftermarket supply is hard to acquire) the spider and dog bones.
Here is what the mopar dog bones and lifters look like.

Oh yeah, and the shorter stock pushrods for the roller cam, as they are shorter than what you have now.
