i am a novice at "rebuilding" an engine. i have a fairly good understanding of the basics and have done a moderate amount of mechanical work through the years. i am rebuilding a '61 d100 for a "driver" for myself. before pulling the engine, i did a compression test and found that the cylinders tested ok except one that seems to have a valve problem. i want to rebuild the top end and replace the main seals. any good referrence material that is a "must" before starting? i am looking for either a general and/or a specific one for a 225.
thanks

See this thread.
