318 LA Rebuild Advice

i'm unclear on the intake and carb-- is that what you currently have or what you are planning on buying? if you currently have them, great. those are excellent for what you want to do.

i see no problem with doing some work on the heads. while it's all apart, and if it's within your budget i'd have a machine shop go thru and check them out and touch up the faces/seats, and drop new seals in. upgrade the springs to match your cam at the same time.

i would probably go with the middle cam, however none of those should get you into any trouble, they're not that wild. you can send yours out and have it reground and have the lifters reground at the same time-- oregon cams is a great place for that, and might even give a recommendation on a specific grind.

be sure to do a new timing set while you're threre.

the gears with those tall tires are gonna be kinda ho-hum, so if you can, maybe get on the hunt for some 3.55's at least. a slightly higher stall converter and shift kit would be a great upgrade as well.

other than that, it's a fairly straight forward mild build. it should run really well.
