65 Barracuda 318 Rebuild, Cam, timing, lifters maybe a kit?

Woah! let's back up the bus. #315 heads are 64 and 65 273 heads and require a specific intake manifold or modified 66 and newer small block manifold. @JeffreyLee , you need to crawl underneath and make sure you don't see "273" cast into the side of the block. It sounds like the "It's a 318" is just a story. It wouldn't hurt to make sure.
Hi Mike,
I know.....freaks me out a little. Casting numbers are clear. I expected heads to just be a matching set of 318 heads. I have the performer intake to go along for the ride. Is this some kind of a hodge-podge?
