My ISP just switched news providers and I can't retrieve some of the information that you guys gave to me a short while back. I may be going through my engine, (stock 455), this next summer, and am entertaining the idea of putting an earlier set of heads on my engine. I found a set of '71 #66 D port 455 heads for sale. Would these work or what other years/numbers would work? Looking for a little better compression and bigger valves. Thanks for answering my question again. HD
