I waas just wondering how much the dome hurts the power. Thanks philr

the dome pistons will have more compression. But yes flat tops are best for 350 engines with 64 cc heads.

4 valve reliefs are cheaper since they fit on both sides 2 need to be different on each side. so it cost more.

dome can hurt power if the head is not right for it. with 64 cc heads its not real easy to buy proper dome pistons that are not in the 12:1 range. BBC and hemis run domes with great success but requires a little know how.
