............................................................................ ...................................................... There has been a variety of solutions given and the choice of method depends on how much mismatch there is. I once had to work with a head where the cams were really tight and just would not rotate freely. Luckily it was at the stage when I was checking how well the cams rotated. My solution was to use some CRC as lube and just keep rotating the cams with vise grips until they freed up. Don't forget that both the caps and head are aluminium, aluminum to Murricans :-) and soft compared with the steel of the camshafts.
You can be really brutal and speed up the process using fine grinding paste but be careful and remember to thoroughly clean afterwards. If you're doing this it would be wise to not torque down the cams fully but carry out this "Honing" in stages. Les in Wellington NZ ...celebrating Bonnie's Record!

I purchased a clean used 2L head from a (non-local) Alfa dealer a number of years ago. The head was already stripped down and did not come with the cam bearing caps. I've already done some porting on the new head so I am reluctant to scrap it and start over, but the missing cam bearing caps makes me worry. Can I use this head or have the missing caps transmographied it into an expensive workbench decoration? ............................................................................ ........................................ -- to be removed from alfa, see http://www.digest.net/bin/digest-subs.cgi or email "unsubscribe alfa" to [email protected]
