Well.......kinda. Keep in mind that the general rule of thumb is only a 3% power increase from 1 full point of compression. So really, I would look into head flow. Maybe save up and have those heads ported or better yet, some aluminum heads. It's well worth the money. If you're going to run iron heads, you don't want worn out guides and seats and it will cost probably as much to rework those as it would to step up to aluminum. Just food for thought. As they say, "it's all in the heads" and that's very true.
