You can get to 500 if you replace the pistons in your engine. You don't have to bore or stroke it. The stock pistons have a huge dish in them. You could probably get away with a $1000 rebuild or less if your willing to do 80% of the build yourself. That $1000 will go towards all the gaskets, bearings, pistons, freeze plugs, and fasteners. Your stock rods will need to be gone over as well as the crank. Bringing up the compression to 9.5 or so will net you some ground on the 500 mark.
I am running a set of D3VE's with 2.19 intake / 1.76 exhaust valves, 3 angle valve seats, milled .020, machined for screw in rocker studs, bronze guides, teflon valve seals, self ported with the air injection bumps ground flat, self polished chambers, and gasket matched to the Stealth intake. Now will all that said I could have bought a new set of aluminum heads for the price of all the machine work. You don't need to do all of that but I would suggest doing the port, chamber, and air injection bump work yourself. The injection bumps restrict the heads a ton. Before I couldn't stick my pinky through the port now I can get my thumb sideways and still have some room. There are stock rocker perch conversions available to put roller rockers on. They aren't the strongest but they will do. Finally with all that said, buy a set of stock 69 or 70 heads. They have all the stuff you want without blowing your budget to kingdom come.
For the block I would suggest mocking the block yourself to see how badly the factory boogered the deck. Mocking the deck involves putting pistons in all 4 corners and measuring how far down the pistons are compared to the block deck. Mine was horrible, the pass front was .047, back pass was .029, driver side front was .033 and the driver back was .048. I had different compressions for all the cylinders. Not to mention the intake ports didn't match the heads that well. Checking this at home before you take it in will allow you tell them you need it or not. Again not a huge issue but does make a difference in the long run. Ditch the bolts for studs, they are way stronger. Remember that spending the money on the block now will pay off later when you have the cash to get those long sought after blue thunder heads you've always wanted.

Aslo i went on to summit racing, which pistion is better? Click here
And if im going to be getting new pistions might as well get either my D3VE heads machined(about how much does that cost?) or even the 462 heads if they will fit unless they already have enough flow for what i need what do you think?
Thanks for all the help

I tried to use the link you posted. Comes up empty with compare option. I bought my pistons from maddog on Ebay. Speed Pro hyper cast coated flat tops with valve reliefs in them. Ran me $250 if I remember right. Ok they are a tad more these days.

How to Build Horsepower, Vol. 1 by David Vizard, Larry Atherton

Ford Performance: Includes All Modern Ford Performance Engines by Pat Ganahl, Larry Schrieb
Max Performance Ford V-8s on a Budget by George Reid
Anyone of these books will give you some answers to any questions you have concerning building an engine. As for the piston link I sent you, they come with the rings and pins. When you buy them Maddog needs to know if you have an overbore and how much to fit them corectly.
Now with all the parts you listed in your first post, you will be able to break the 500 mark. The only part I would leave out for now would be the MSD ignition. The system is an add on that wont cost you anything more then the time to install it. I think there are a few people that will agree that an MSD ignition is not needed to get you going. A stock Ford dura spark system is all that is needed to get the motor running down the road. If you need one let me know I have my old one sitting in a box in my garage taking up space. You can have it for $50 and shipping. I think it needs a new gear but then again I think I am a perfectionist.
The head work will vary depending on where you live. Best info I can give is to call a few machine shops and see what they all charge for different services. A good one will listen to what you are trying to achieve and ask what your block build and cam you have in mind.
