I have a 355 chevy with small dome pistons in it. I recently had a set of holley alluminum heads on it and the best I got out of the engine was a 12.58 in the 1/4. Everyone that I have spoken to about the engine said that the heads were to small. So I sold them Nobody can seem to give me a strait answer on what heads to go with. If anyone has any suggestions please let me know. Thank you
