I remember back in the 1960s when a guy saw a pair of aluminum heads that he liked he bought them. Then he went to the parts store to get a set of head gaskets. Probably bought what the parts guy told him was best. He installed the heads without any knowledge of "squish". He was so proud of his cool looking engine. The engine ran well and he was happy. Is this scenario not possible anymore for the average guy? Do we all need to measure squish for an old stocker engine to run good enough for weekend drives?
