stock heads will limit you on power as far as what the motor is capable of. plus if your bronco is speed density,you should probably change it to mass air. or you could save a %$#@load of money and out a carb on it.

If your not running mas alrealy then your going to be bettor off with mas on that combination. You will need to up your injector size and I would get a larger Mas from Pro-M with a map to give to your computer guy to set it all up for that much motor. The 19lb injectors were barely adequate for the stock engine. Your computer is fairly limited on the mods that can be performed to it. You might look into a Mustang computer to run your works. The computer you choose will depend also on which tranny your Bronco has in her now. You will have other mechanical upgrades that should be performed to fully achieve the HP potential of that big of a small block.

19's will support a MAX of 243.5 HP with the stock fuel pressure. I would hope a stroker of that size is making alot more power than that. Depending on the engine build, 30lb injectors will support 384 HP, so the 30's are probably more in the ballpark for this engine.
1.93's or < valve size and dependability issues, why is that?
