The Magnum heads flow much better, and the closed chamber design will pick you up about a 1/2 point or so of compression (maybe a little more on a 318). Scott B. "I'm a self-made man...

Last three digits of the casting number are 302. While not as good as the magnum heads, they require no other parts swapping and should be available at a salvage yard near you. Buy a Hybrid!!
