I find that soft wire brush on a bench grinder/buffer is fine for aluminium, you know the one that is thin wavy wires with a brass coating, brings gasket trace right off
:doh: lol, well as I have to wait 12 weeks for my heads to arrive and I have not even ordered the bearings from aus yet I expect you will beat me to it so let me know how the cam is!
Finished cleaning up all the paper gaskets finally. . What a basterd! Ended up using some 5mm perspex and a bit of a clean up with a fine brass wheel as suggested by some noisy sod also pressed in my new can bearings so now I can start reconstruction!
I used a bit more perspex(48mm wide) to push against the bearings on some threaded rod also had a bit of ali on the back of the perspex to keep it at the right angle, ill do one of my famous pics
