Finally getting around to starting the rebuild.
Bought so far: headman headers, offy dp, and holly 390.
Next up: felpro gasket set, comp 260 cam kit w/lifters and timing gears, and currently searching for a 240 head.
Any advice on where to locate a 240 head?
What pistons should I go for? I don't mind using a higher grade gas.

I am sure someone else will comment something that has more experience with these but make sure that you get pistons with some valve clearance since you are getting a 260 cam. Dont want to make the mistake of hitting a valve.

Use studs for the int/exh, with crimp nuts, grade eight. Not only is it easier to install, they prevent leaks because they don't loosen. Use Mr. Gasket #260 for int/exh. Even though I you use a Fel-pro kit, I'd still buy the $50 Fel-pro head gasket if you bump the compression, either that or use studs for the head too. I shaved my block .020, and the same on the head, and after 1k miles when I took it apart with a Felpro head gasket, I could see where the normal kit gasket was ready to fail between the cylinders. That scared me.
Use copper anti sieze on the studs into the head. Use high temp copper rtv around exhaust ports on both sides of int/exh gasket. Prime the oil pump with a drill motor and pump oil out all rockers before the start.
Use an intake heating plate or you'll be back on here complaining about driveability.
