I'm no expert Graham but in the 90s I had a Phil Read Rep with cam towers that where goosed - had them line bored and had some shells made for bottom of towers and complete new phosy bronze caps made that 'clamped' in the bottom shell's - not standard spec but worked for several thousand miles while I had it - hope that makes sense after several Madererian beers on holiday!

I know this method Phil, but it also weakens the towers. At this time we line bore the towers and metal spray the journals on the cam shaft and then grind to fit. This can only be done it the tower has only had minimum damage.

That's me told - back to my beer! No seriously, when I did mine, I was able to machine can bearings slightly to get any wear marks out then have them case hardened then machined towers/caps to suit - it's all down to budget I suppose - I was working at BAE at the time and cost nothing! Now back to the Madererian beer!
