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

You be in big trouble then
To properly get the most from aluminum heads, the Dcr needs to be way up there.
If all you want is 155/160 psi pressure you are leaving the best, or maybe the second best of those heads , untapped.
They come alive at 170 psi, become a terror at 185, and some guys are running 200PSI or a tic over, still on pumpgas. I have been to 185 on 87E10 for 4 years, and that was the best doggone street combo I ever had.
It is very difficult/expensive to get to 185plus with a 318.

If I get to do it over again in my life, I'm gonna push 200psi, and
there is no way I would run stock arms or pushrods, and
if I'm buying arms, they will be 1.6s.Then, the cam will be for street use, so about mid 220s @.050. This combo will make so much torque, I will have to run a traction aid, so it won't spinout at every traffic-lite, and so I can pass slower traffic on the hiway using WOT, and not get killed when changing lanes.

For your teener to get 180psi at 2600ft with a modest cam (64*ICA), will require about 11.5 Scr, to get 9.1Dcr/180psi@133VP.
How are you gonna get to 11.5 with your 318? This requires a chamber volume of 652/10.5=62.1cc good luck. 60779s are born at 63cc, you need to run a minimum Q of mid 20s so that's the 6.5cc gasket. the cam you run is probably gonna want some eyebrows, and with the 2.02s this is gonna be about 5cc; so at Zero deck your chambers are already; 62+6.5+5=73.5, making your static CR 9.87....... 9.87 is a long long way from 11.5

With the same modest cam as before (64*ICA), your new numbers are
9.87/7.88/146/109VP....... 109 is less than what a smog 318 makes, so you are gonna be a very unhappy man til the engine gets up on the cam, probably at about 3500rpm. And the next expense will be a big TC, followed hotly by rear gears.
So now you have heads capable of 400hp easy enough, and a cam that might make 300 in your 318 combo, and the damn car can't even hardly spin the tires, unless you spend another $1000 on a TC and gears..

Now don't get me wrong; I have those heads on my 367 which at zero deck makes about 11.1 Scr, with the only additional expense being the decking. And I can say with complete confidence that these are really nice heads, in and of themselves, but man they really come alive at over 185psi. And I can also say, that at a predicted 146psi, I'd rather have iron heads, and closed chambers are waaay better for a streeter.
Those are my opinions.
To be fair, I have never put aluminum heads on any 318, much less a low-compression one. And the principle factor in that is the expense of getting the Dcr up, to use a proper cam, to get the most out of those heads.

Now I'll tell you thing, if you put the factory cam back in there( with it's 48* ICA) and the Eddies, well then at zero deck, she will be a torque monster, with new numbers of
9.87/8.73Dcr/169psi@141VP. With these numbers, you can keep your current TC and current gears, and will have a tire-fryer probably all the way thru first gear (if the TC does it's job) to 4800rpm or over 50 mph with 2.71zzzzzzzzz.
But the clincher is you can bolt on some iron heads, and leave the pistons down in the holes a bit, and do almost the exact same thing, with maybe a lil less tirespin on the top.
With the pistons down .057, and a .028 gasket, flat-tops no eyebrows, and closed chamber 1967 up heads @60cc, your engine can make
9.4scr/7.3/158psi@132VP, still with the factory ICA of 48* . 132 is a very good number for a 318. A TC and gears will make this very competitive as a streeter, for waaaay less money than the 60779s, and the bonus is that this combo will probably be very happy with 89 gas, less when cruising.
And you have room to grow; with the pistons down at .057 you can add enough compression by decking, to run a cam 2 or three sizes bigger, and not suffer the loss-of-low-rpm that normally accompanies such a change.
The point is this; the simultaneous loss of cylinder pressure of 63cc heads, over your spec'd 57s, and them also being aluminum, is, IMO a poor trade-off. Will the Eddies increase your power? Maybe, with camming. But the trade off is slanty torque at low-rpm, requiring the bigger TC and gears to compensate; poor trade-offs for a streeter; which needs grunt every single time you take off, and every single time it shifts; especially into second.
