If you need to stick to 3K then don't get wrapped up in the "Might as wells" everyone here will tell you to go for, particularly in your cylinder heads. Check the guides. If it needs guides have them done, and get a valve job. If it doesn't need guides a valve job is your call, you can just hand lap them. Don't buy new valves. Do not pass go. Do not collect 200 dollars, and don't let everyone talk you into new valves, hardened seats, and guides so that they can switch you onto aluminum heads for 50 dollars more, because 3K doesn't have the budget for that.
You will need springs to match whatever cam you want to run and locks and retainers to match the springs.
Do you have any supporting mods already like headers, intake, or carb?
Buy decent pistons for decent compression.
Is 3K including assembly?

he won't ahave quench with those heads but that's ok. get yourself the 'big' summit cam, new valve springs to match and keep the investment in the heads down. get a set of trw2355 pistons. they are close enough in weight to the stock pistons that you shouldn't need to rebalance and they will give you a decent compression ratio unlike those stock 73 pistons. have the block hot tanked, bored and honed and new cam bearings installed. that's it, no room in the budget for more. have your crank ground or polished for new bearings. have your stock rods reconditioned or buy redone stockers. they can often be had on ebay for cheap.
Good advise right here. Have the block milled for zero deck clearance with those pistons. The Summit cam is good for the price.

If it is running and driving now, do not take it out to rebuild it, mostly on that budget. If you are not good friends with the machine shop then you will be spending way more than your wish. Find another complete engine and use it to rebuild. This way if you go over budget (which you will) the car is not sitting there. Plan on several hundred in extras as well, couple oil changes, new plugs, wires, hoses, belts, carb rebuild, ect. little stuff that often gets overlooked and adds up fast.

Build a solid bottom end, then you have the foundation for anything you want to do later. I run steel cranks and forged pistons in damn near everything just because. That way I never have to worry about which turn the build takes later. Cast iron heads will make good horse power, yes you can get more out of something else but that is always the case.
Careful, your character's showing!

The prices listed were from last year, and I was just looking up the forged lightweight Speed Pro piston LW2355F30, and it is hard to find on line. The piston is a lighter weight (by about 100 grams) L2355F30 piston, and when I priced them last year there was only a few dollars difference (looked like a great deal for a forged piston.) You would have to call Summit or your machine shop to see what the cost is and how long to get them. Speed Pro still lists them in their catalog. I have had the machine shop beat some of the mail order prices, so it's worth checking. Work with the machine shop to get the correct size overbore pistons, and bearings if the turn the crank. I also noticed I had two gasket sets in the list, so that should knock about $50 off the total. The list also added 0.020" head gaskets for more compression with stock iron heads, but the Fel-Pro gasket kits include 0.040" head gaskets which work good with the closed chamber aluminum heads. The viton rear main seal is expensive, but seals better than the rubber ones in the gasket kit. Both pistons I listed use 1/16" thick piston rings which is different than the standard 5/64" rings, and the rings listed are file-fit piston rings. I also listed a more expensive cam bearing kit than standard. I install my cam bearings (have the tools), but your machine shop should install and size the cam bearing for you, unless you know how. Make sure to have them check your cam for fit before you take the block home. Also, have them install the ARP rod bolts before resizing the rods.
