Hey everybody. I have spent the last year on the SOHC forum as I restored my CB550F. This year my winter project is a 1973 CL450 so I had to switch boards! Anyway, the new project is a little rough. The frame, tank, and pipes are in good shape, but the engine is in pieces. I have 3 heads and two bottoms. I really don't know which one to restore. How can I tell which engine is the best one to start with. Also, the rims are pretty rusty and pitted. Any advice from those that have recently rebuilt the engine up from scratch would be great. Thanks, and I will be on here a lot, trust me. I hope to start a build thread as I restore the bike as well.
