For a single exhaust pick the longest muffler you can get under there.The longer the case the quieter the muffler.On a single exhaust 305 it will only be so loud anyway.It depends on what you want. A 20" case dynomax Super Turbo will sound nice and give a little more flow.

I have used many of these to put a Holley/Edelbrock on a spread bore performer intake on my big block Dodge motors. Some say they are better...
On a stock cast iron intake they recommend this;

Or if you have some extra cash look for an Edelbrock 2701 new or used...
Hard to go wrong with either one. For your setup I like the smaller intake runner of the Brodix but for compression I like the 113cc of the Trick Flow head. I would be looking for at least 9.0-1 and 9.5-1 would be better.
It will run fine with either head. Go with the most affordable of the...
I realize I am in the minority here but I wanted mine quiet. I have magnaflow before the axle and dynomax super turbo under the bed just before the bumper. It helps I had two sets of mufflers I wasn't using so there you have it.
454 with long tube headers and 2.5 pipes.
If you don't go hydraulic roller I don't know that I would trust a flat tappet cam. Heads would certainly help. 64cc or smaller ups the compression and will wake it up even with the stock Cam. 1.6 roller tip rockers for fun.Use the added flow of new heads.
Sure a used aluminum intake...
Just finished rebuilding the front end,new shocks all around,and an alignment. Rides and steers better than an old rust bucket should. With a front sway are it would be about perfect.. What is a good source for a stock or slightly bigger front swaybar for our trucks?
I actually drove mine yesterday. And the battery left me waiting for a jump after dropping my son's bicycle off to be repaired.
Have it on the charger now but I don't think it will recover. Less than 2 years old so full warranty.
If your pistons and bore are good no reason to change them IMO. If they are out of spec then a dome pistons that puts you at 9.0-9.5-1 will help power everywhere.
I bought a cheap(new) limited slip and used factory gear set off of eBay for mine.Horrible I know but I'm not spending a ton of money on a 10 bolt in my bucket of rust. Not a ton of miles yet but it pulls both tires hard.
That is a mild cam and should work even with the stock compression. That being said it wouldn't hurt to deck the block a little (if for no other reason than to make sure it is flat and square) and have them mill the heads a little as well. Thin head gasket and it all adds up.
I would have them...
