best head for 318 street car

Whats important regarding head question on a 318 is port size or cross section area. You need all the ram effect you my get to wake up the 318. Its too easy to pick a too big head. I think the eq or x or j or 302 all are a good start, and if you invest some dollars, You take it to a porting shop and pay them to get the port to the correct size. (File or epoxy) The hard deal is to make the port flow a high number on the correct port size! If you put your engine data into pipemax by larry meaux(http://maxracesoftware.com/pipemax36xp2.htm) it will give you the correct port size. Thats what I think
