engine math! milling heads + intake

If they went from 72 cc's to 60 cc's then they had to cut about .060 off the deck and .072 or so off the intake side of the heads. To me it would be better to use the 318 heads and use the stock size intake valves or if your just itching to put larger valves in then go to the 1.88 intake valves instead of going to the 2.02 that they did in the mag. artical. I know that they used the 360 head castings but the intake runners are a bit large for the street on a 318's bore size. The velocity will suffer and you'll be changing the heads before you know it. I have a setup like this with the 302 heads and it makes well over 400 HP and I used the KB 167 pistons and square decked the block to be just out of the deck about .018 or a build like the 340 HP engines but in a 318 block. This works very well and without any special parts other than pistons.
