Looking for a little more power out of a 318

Actually, thats not what i ment, lol i ment if you dont have them, there are better heads to chose from. The 302's need alot of work to flow as well as other heads with less work. A little "clean up" on a set of 302's is a waste of money IMO, unless you do it your self, and still then, it would be hard to get equal numbers out of these heads.
A better choice would be a 360 headd with a 1.88 vale to keep the velocity up. But the ultimite choice would be a set of magnums.

Your not looking for equal numbers out of the 318 head to compete with the 360 head, the issue is velocity in the port and you have to keep in mind the the short stroke and bore size of the 318 will work with great and efficent vs a 360 head.

It's an issue of the size of the bore and stroke combo and the volume of the port. Of course how well the port flows is an issue, but if the port is large and flows the number sought it will be dogish and get it's *** whooopped by a smaller head and valve combo with a port constantly moving aair at a high rate rather than waiting until you can use the larger head.

The small port head cleaned up and port matched is a better head for a mild 318 than a 1.88 360 head box stock. A 1.60 valve for exhaust on the teen head is a good idea.
It could work out cheaper - easy - than a purchase of a 360 head.
