Then again theres the eq magnums as well.
Your opinion has been noted,lol.
There are some here who do not like the magnum.
I for one cant argue with cheap chev price roller rockers,and a boost to 9:1! They make great street heads and the nice thing is they'll make 400h.p on your 318 with no porting.Magnums also produce a very flat and fat torque curve
All heads crack eventually. Id run em without fear myself. I still have my pair here and a 360 waiting for them. Some good porting on the magnums and I think 450 hp is not hard to achieve.
