I can help, but I'll need to know how you plan on using the engine, street, street/strip, or all out racing? If want to build power and have reliability, I would suggest using a strong, but light weight rotating assembly. I have a 474 with a 4.25" Eagle forged crank, Eagle "H" beam rods, and Ross Pistons that spins to 7600 regularly, but I think that the most important thing that gives me the reliability is the Titan oil pump! I'm sure that the engine would stay together, with a stock gear to gear type pump, if I didn't spin it past 6200 to 6400, but why take the chance? Now, if your car won't see a lot of racing, I can't see putting a $1000 oil pump in it. As for gear, I need to know what transmission, tire diameter, total weight, and as I said before, your usage.

Bill

You already know those heads are no good, don't know if you bothered to read the info or look at any of the pile of links you were given HERE . Hopefully you'll get someone who will spoon it to you a little bit at a time.

Good luck and see ya. lol
