302's on the 360 ?

But keep in mind that it's not just the heads that make it work, it's the whole combination of parts that makes it work like it should. These heads only flow 218 @ .450 but still more than enough to make over 500 HP. Also it's how we machine the rest of the componets that helps this out too. Watch the fine details and have it machined to the T's and it will work for you as it does for us.
You can trick the flow to produce up to 30% more than the heads actually flow and in this case we have them working like a set of heads that flow almost 230 cfm's.
