Default Re: Pre-Unit Case "use or not"

Thanks for all the comments. I have more confidence in proceeding with what I have.

The guy I am dealing with locally has years and years of experience with Triumphs, and has the same sentiment. He also told me to look at the condition of the head as far as hairline cracks from the bolt holes inward towards the valves...... sure enough I found cracks. He said all of the 8 bolt heads end up developing cracks eventually; so I am in the process of gathering parts to change over to the 9 bolt later model cylinders and head.

On that note do the Pre-Unit rocker boxes mate up to later model heads at all?
