how to get power from a 318

Rumble, It wasn't the 302 heads that have the cracking problem, It's the magnum heads that have the problem. Now I'm sure that the heads will crack but haven't had that kind of problem as of late. They are fairly thick between the seats, or they have been severly over heated. I do agree with you on the rest of the comments, but he could stand a little more cam, something like a 280H comp. good vacume and torque, lots of low end power with the intake and carb combo. stated.
I agree with the stock heads (318s) and valves as this will be a big gain in the performance department with some minor work, bowl blending and gasket matching. This should be fun for the street!
