was wondering if putting these heads on my 40 over 350 with flat tops would be worth it or should i stick to my stock 350 heads. im putting a edelbrock preformer rpm intake and a 750 holly on it with a lunatti bracket master 2 with a lift of 515 and a 2500 stall converter. what kind of power can i expect from all of this and was wondering about the compretion ratio??
